#### Answer

w=24

#### Work Step by Step

We first subtract by w/3 on both sides to get that $3=w/3 -5$. We need to get the w alone. Thus, we cancel out the subtraction by adding 5 on both sides. This leaves us with the equation $w/3=8.$ In order to cancel out division, we use multiplication, so we multiply both sides by 3 to get that w=24. We plug 24 in for w and confirm that our answer is, indeed, correct.
