Please help in Math!? What value of y makes the equation true?

Zepler [3.9K]

$\frac{-7}{12} = \frac{y}{-36}$

First, simplify $\frac{y}{-36}$ to $- \frac{y}{36}$ / Your problem should look like: $- \frac{7}{12} = -\frac{y}{36}$
Second, multiply both sides by 36. / Your problem should look like: $-21=-y$
Third, multiply both sides by -1. / Your problem should look like: $21 = y$
Fourth, switch your sides. / Your problem should look like: $y = 21$

Answer: C) 21
