# How do you solve -180=15m?

Dec 13, 2017

$m = - 12$

#### Explanation:

To solve this we must divide each of the sides by $15$, what you do to one side, you do to the other

$\implies - \frac{180}{15} = \frac{15 m}{15}$

Now we see $- \frac{180}{15}$ cancels to give to: $- \frac{12}{1} = - 12$

And we know $\frac{15}{15} = 1$ as anything divided by itself equals 1

$\implies - 12 = m$

$m = - 12$
