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

1. -6m = 72

Divide both sides by -6

[tex]\begin{gathered} \frac{-6m}{-6}=\frac{72}{-6} \\ \end{gathered}[/tex]

m = -12

2. 5x = -30

Divide both sides by 5

[tex]\frac{5x}{5}=\frac{-30}{5}[/tex]

x = -6

3. n/3 = 21

Multiply both sides by 3

[tex]\frac{n}{3}\times3=21\times3[/tex]

n = 63

4.

[tex]\frac{y}{-18}=-6[/tex]

Multiply both sides by -18

[tex]\frac{y}{-18}\times-18=-6\times-18[/tex]

y = 108
