What number should be added to both sides of the equation x - 7 = 1 to solve for the value of x ?
To solve for the value of x, the same number should be added to both sides of the equation x - 7 = 1. To isolate the variable x, we need to get rid of the -7 on the left side of the equation. To do that, we should add 7 to both sides of the equation. Adding 7 to both sides of the equation results in:
x - 7 + 7 = 1 + 7
On the left side, the -7 and +7 cancel out, leaving us with:
x = 1 + 7
And on the right side, we have:
x = 8
Therefore, the value of x is 8.
To solve for the value of x in the equation x - 7 = 1, you should add 7 to both sides of the equation.
Step 1: Start with the equation x - 7 = 1.
Step 2: Add 7 to both sides to isolate the variable x.
(x - 7) + 7 = 1 + 7.
This simplifies to x = 8.
Step 3: The value of x is 8.
To solve for the value of x in the equation x - 7 = 1, we need to isolate the variable x on one side of the equation.
Since the constant term on the right side of the equation is 1, we can add a number to both sides of the equation to eliminate the -7 on the left side.
To cancel out the -7 on the left side, we need to add 7 to both sides of the equation.
Adding 7 to both sides of the equation, we get:
x - 7 + 7 = 1 + 7
Simplifying, we have:
x = 8
Therefore, to solve for the value of x, we need to add 7 to both sides of the equation.
