Question

Which describes the first step in solving the equation 4x - 7 = -15?

Answer 1

Add 7 to both sides

Explanation:

You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.

Then you would get 4x = -8.

Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.

x = -2
