#### Answer

$t=2.7$

#### Work Step by Step

We need to get the t alone. Thus, we cancel out the addition by subtracting 3 on both sides. This leaves us with the equation $-27=-10t.$ In order to cancel out multiplication, we use division, so we divide both sides by -10 to get that $t=2.7$. We plug 2.7 in for t and confirm that our answer is, indeed, correct.
