Answer
$x=-5$
Work Step by Step
We need to get the x alone. Thus, we cancel out the addition by subtracting 12 on both sides. This leaves us with the equation $ 5x=-25.$ In order to cancel out multiplication, we use division, so we divide both sides by 5 to get that $x=-5$. We plug -5 in for x and confirm that our answer is, indeed, correct.
