Answer
$g=8$
Work Step by Step
We need to get the g alone. In order to cancel out division, we use multiplication, so we multiply both sides by 3 to get that $g-3=5.$ We now cancel out the subtraction by adding 3 on both sides, giving us a final answer of $ g=8$. We plug 8 in for g and confirm that our answer is, indeed, correct.
