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