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, you need to isolate the variable x on one side of the equation.
To do this, you can add 7 to both sides of the equation:
(x - 7) + 7 = 1 + 7
On the left side, the -7 and +7 cancel each other out, leaving you with just x:
x = 1 + 7
Simplifying the right side gives you:
x = 8
Therefore, to solve for the value of x, you need to add 7 to both sides of the equation.
