$g=4.27$

We need to get the g alone. Thus, we cancel out the addition by subtracting 3.89 on both sides. This leaves us with the equation $21.35=5g$. In order to cancel out multiplication, we use division, so we divide both sides by 5 to get that $g=4.27$. We plug 4.27 in for g and confirm that our answer is, indeed, correct.
