#### Answer

t=2.7

#### Work Step by Step

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