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 number should be added to both sides of the equation x - 7/8 = -5
what number should be added to both sides of the equation x - 7/8 = -5 to find the value of x
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.
