## Algebra 1: Common Core (15th Edition)

We find that $5 - x/3 = -15$. We need to get the x alone. Thus, we cancel out the addition by subtracting 5 on both sides. This leaves us with the equation $-x/3=-20$. In order to cancel out division, we use multiplication, so we multiply both sides by -3 to get that x=60. We plug 60 in for x and confirm that our answer is, indeed, correct.
