To solve for x, you need to isolate x on one side of the equation. Adding the same number to both sides of an equation maintains its balance. In this case, to isolate x, you should add 7 to both sides of the equation since the term -7 is already isolated on the left side:
(x - 7) + 7 = 1 + 7
Simplifying:
x - 7 + 7 = 1 + 7
x = 8
what number should be added to both sides of the equation x-7=1
