Answer

$t=-24$

Work Step by Step

We need to get the t alone, so we cancel out the subtraction by adding 7 on both sides. This leaves us with the equation $5/8t=-15$. We need to get the t alone, so we use multiplication to cancel out the fraction, 5/8. Thus, we multiply by the reciprocal, 8/5, to obtain an answer of $t=-24$. We plug -24 in for t and confirm that our answer is, indeed, correct.
