Work Step by Step
We first combine like terms to find that $10t+7=-33$ We need to get the t alone. Thus, we cancel out the addition by subtracting 7 on both sides. This leaves us with the equation $10t=-40$. In order to cancel out multiplication, we use division, so we divide both sides of the equation by 10 to get that $t=-4$. We plug -4 in for t and confirm that our answer is, indeed, correct.
