$(g+4)-3g=1+g \\\\ -2g+4=1+g \\\\ -3g+4=1 \\\\ -3g=-3 \\\\ g=1$ We first add like terms on the right side of the equation to simplify. We then subtract by g on both sides. Next, we subtract by 4 on both sides. Finally, we divide by -3 to get that g=1. We plug 1 in for g and confirm that our answer is, indeed, correct.
