Answer
$x=-3$
Work Step by Step
We need to get the x alone, so we cancel out the addition by subtracting 3 on both sides. This leaves us with the equation $5x=-15$. We cancel out multiplication by using division, so we divide both sides of the equation by 5 to get that $x=-3$. We plug -3 in for x and confirm that our answer is, indeed, correct.
