Question

Solving one-step equation by multiplication and division 1. -6m = 72 2. 5x = -303. n/3 = 214. y/-18 = -6

Answer 1

We want to solve the given one-step equations by multiplication and division

1. -6m = 72

Divide both sides by -6

$\begin{gathered} \frac{-6m}{-6}=\frac{72}{-6} \\ \end{gathered}$

m = -12

2. 5x = -30

Divide both sides by 5

$\frac{5x}{5}=\frac{-30}{5}$

x = -6

3. n/3 = 21

Multiply both sides by 3

$\frac{n}{3}\times3=21\times3$

n = 63

4.

$\frac{y}{-18}=-6$

Multiply both sides by -18

$\frac{y}{-18}\times-18=-6\times-18$

y = 108
