Work Step by Step

We need to get the b alone, so we cancel out the subtraction by adding 5 on both sides. This leaves us with the equation b/4=12. We cancel out division using 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.
