Work Step by Step
We need to get the g alone. Thus, we cancel out the addition by subtracting 1.12 on both sides. This leaves us with the equation $1.25g=7.5$. In order to cancel out multiplication, we use division, so we divide both sides by 1.25 to get that $g=6$. We plug 6 in for g and confirm that our answer is, indeed, correct.
