what number should be added to both sides of the equation x-7=1 to solve the value of x
To determine which equation has a solution of -1/2, we will evaluate each equation using -1/2 as the value of x.
1) x + 1 = 1/2
Using x = -1/2:
(-1/2) + 1 = 1/2
1/2 = 1/2
The equation x + 1 = 1/2 is satisfied when x = -1/2.
2) x + 1/2 = -1
Using x = -1/2:
(-1/2) + 1/2 = -1
0 = -1
The equation x + 1/2 = -1 is not satisfied when x = -1/2.
3) x - 1/2 = 1
Using x = -1/2:
(-1/2) - 1/2 = 1
-1 = 1
The equation x - 1/2 = 1 is not satisfied when x = -1/2.
4) x - 1 = -1/2
Using x = -1/2:
(-1/2) - 1 = -1/2
-1.5 = -1/2
The equation x - 1 = -1/2 is not satisfied when x = -1/2.
Based on our evaluations, the only equation that has a solution of -1/2 is x + 1 = 1/2.

What is the value of x in the equation x + 0.97 = -2
What is the solution of the equation x - 9/4 = -3/8?
To solve the equation x - 9/4 = -3/8, we need to isolate x.
First, let's add 9/4 to both sides of the equation:
x - 9/4 + 9/4 = -3/8 + 9/4
This simplifies to:
x = -3/8 + 9/4
To add these fractions, we need a common denominator. The lowest common multiple of 8 and 4 is 8, so we can rewrite the fractions with the common denominator of 8:
x = -3/8 + 9/4
x = -3/8 + 18/8
x = (18 - 3)/8
x = 15/8
Therefore, the solution to the equation x - 9/4 = -3/8 is x = 15/8.
what number should be added to both sides of the equation x + 11 = -17 to solve the value of x
To solve for the value of x in the equation x + 11 = -17, we need to isolate x by subtracting 11 from both sides of the equation.
By subtracting 11 from both sides, we get:
x + 11 - 11 = -17 - 11
Simplifying the equation, we have:
x = -17 - 11
To add -17 and -11, we simply add the two numbers together:
x = -28
Therefore, the value of x is -28.

To solve the equation x + 23 = 9, we need to isolate x by subtracting 23 from both sides of the equation.
By subtracting 23 from both sides, we get:
x + 23 - 23 = 9 - 23
Simplifying the equation, we have:
x = -14
Therefore, the solution to the equation x + 23 = 9 is x = -14.
Which of the following equations has a solution of -8?
To determine which equation has a solution of -8, we need to evaluate each equation using -8 as the value of x.
1) x + 5 = -3
Using -8 as the value of x:
-8 + 5 = -3
-3 = -3
The equation x + 5 = -3 is not satisfied when x = -8.
2) 2x - 6 = -22
Using -8 as the value of x:
2(-8) - 6 = -22
-16 - 6 = -22
-22 = -22
The equation 2x - 6 = -22 is satisfied when x = -8.
3) 4x + 10 = 2
Using -8 as the value of x:
4(-8) + 10 = 2
-32 + 10 = 2
-22 = 2
The equation 4x + 10 = 2 is not satisfied when x = -8.
Based on our evaluations, the equation 2x - 6 = -22 has a solution of -8.
Which answer
x + 3 = -11
x - 8 = 0
x - 10 = 2
x - 4 = -12
The equation that has a solution of -8 is:
x + 3 = -11
Which of the following should be done to both sides of the equation x - 3.41 = -19 to solve the value of x
To solve for the value of x in the equation x - 3.41 = -19, we need to add 3.41 to both sides of the equation.
By adding 3.41 to both sides, we get:
x - 3.41 + 3.41 = -19 + 3.41
Simplifying the equation, we have:
x = -19 + 3.41
To add -19 and 3.41, we simply add the two numbers together:
x = -15.59
Therefore, the value of x is -15.59.
Which answer
Subtract 19
Add 3.41
Subtract 3.41
Add 19
The correct answer is to add 3.41 to both sides of the equation.
Which of the following equations has a solution of -1/2 (1 point)
x + 1 = 1/2
x + 1/2 = -1
x - 1/2 = 1
x - 1 = -1/2
To solve for the value of x in the equation x - 7 = 1, we need to add 7 to both sides of the equation.
By adding 7 to both sides, we get:
x - 7 + 7 = 1 + 7
Simplifying the equation, we have:
x = 8
Therefore, the value of x is 8.
To solve for the value of x in the equation x + 0.97 = -2, we need to isolate x by subtracting 0.97 from both sides of the equation:
x + 0.97 - 0.97 = -2 - 0.97
Simplifying the equation, we have:
x = -2 - 0.97
To subtract the numbers on the right side, we can find a common denominator. The denominator of 1 in 0.97 can be written as 100/100. So, we have:
x = -2 - 0.97(100/100)
x = -2 - 97/100
Next, to combine the terms on the right side of the equation, we need a common denominator. The denominator of 100 is already common, so we can simply add the numerators:
x = (-2 * 100 - 97) / 100
x = (-200 - 97) / 100
x = -297 / 100
Therefore, the value of x is -297/100.
To solve the equation x - 7/8 = -5 and find the value of x, we need to add 7/8 to both sides of the equation.
By adding 7/8 to both sides, we get:
x - 7/8 + 7/8 = -5 + 7/8
Simplifying the equation, we have:
x = -5 + 7/8
To add -5 and 7/8, we need to find a common denominator. The denominator of 8 is already common, so we have:
x = -5(8/8) + 7/8
x = -40/8 + 7/8
To add the fractions, the denominators must be the same. In this case, they are already the same, so we can add the numerators:
x = (-40 + 7)/8
x = -33/8
Therefore, the value of x is -33/8.
To solve the equation x - 7/8 = -5 and find the value of x, we need to add 7/8 to both sides of the equation.
By adding 7/8 to both sides, we get:
x - 7/8 + 7/8 = -5 + 7/8
Simplifying the equation, we have:
x = -5 + 7/8
To combine the terms on the right side of the equation, we need to find a common denominator. The denominator of 8 is already common, so we have:
x = -5(8/8) + 7/8
x = -40/8 + 7/8
To add the fractions, the denominators remain the same. Therefore, we can simply add the numerators:
x = (-40 + 7)/8
x = -33/8
Therefore, the value of x is -33/8.
