To solve for the value of x in the equation x−7=1, we need to isolate the variable x by adding the same number to both sides of the equation. In this case, we want to find the number that, when added to both sides, will cancel out the -7 on the left side.
To do this, we 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 us with just x:
x = 8
Therefore, the number that should be added to both sides of the equation x−7=1 to solve for the value of x is 7.
What number should be added to both sides of the equation x−7=1 to solve for the value of x ?
