What is the solution of the equation x−7=1 ?(1 point) $$ Skip to navigation
The solution of the equation x-7=1 is x=8.
What number should be added to both sides of the equation x − 7/8 = −5 to find the value of x ?(1 point)
To find the value of x in the equation x - 7/8 = -5, we need to isolate x. To do this, we need to add the same number to both sides of the equation.
To determine what number to add, we can look at the constant term on the right side, which is -5. We want to eliminate this constant term by adding a number. Since the coefficient of x is 1, we can add 5 to both sides to cancel out the -5 on the right side.
So, the number that should be added to both sides of the equation is 5.

Apologies for the incorrect response. Let's correct it:
To find the value of x in the equation x - 7/8 = -5, we need to isolate x by adding the same number to both sides of the equation.
To determine what number to add, we can look at the constant term on the right side, which is -5. We want to eliminate this constant term by adding a number. In this case, we need to add 7/8 to both sides of the equation to isolate x.
Adding 7/8 to both sides:
x - 7/8 + 7/8 = -5 + 7/8
x = -5 + 7/8
Now, we need to simplify the right side:
x = -40/8 + 7/8 = (-40 + 7)/8 = -33/8
So, the value of x is -33/8.
To find the solution of the equation x - 7 = 1, you need to isolate the variable x.
Here are the steps:
Step 1: Add 7 to both sides of the equation:
x - 7 + 7 = 1 + 7
This simplifies to:
x = 8
So, the solution to the equation x - 7 = 1 is x = 8.
To find the solution of the equation x - 7 = 1, we need to isolate the variable x. Here's how you can do it:
1. Start with the equation: x - 7 = 1.
2. To isolate x, we want to get rid of the -7 on the left side of the equation. We can do this by adding 7 to both sides of the equation.
3. Add 7 to both sides: x - 7 + 7 = 1 + 7.
On the left side, the -7 and +7 cancel out, leaving us with just x: x = 1 + 7.
4. Simplify the right side of the equation by adding 1 and 7: x = 8.
So, the solution to the equation x - 7 = 1 is x = 8.
