Answer

$t=-70$

Work Step by Step

We first simplify the equation to: $t/5 -3 =-17$. We need to get the t alone, so we cancel out the subtraction by adding 3 on both sides. This leaves us with the equation $t/5=-14$. We cancel out division using multiplication, so we multiply both sides by 5 to get that t=-70. We plug -70 in for t and confirm that our answer is, indeed, correct.
