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

We need to get the b alone. Thus, we cancel out the subtraction by adding 5 on both sides. This leaves us with the equation $b/4=12$. In order to cancel out division, we use multiplication, so we multiply both sides by 4 to get that b=48. We plug 48 in for b and confirm that our answer is, indeed, correct.
