# How do you find the unknown value of 3timesa=12?

Jun 13, 2018

$a = 4$

#### Explanation:

$3 \times a = 12$

To find the value of the unknown value $a$, we have to isolate it (make it by itself). To do that, we can divide both sides by $\textcolor{b l u e}{3}$:
$\frac{3 \times a}{\textcolor{b l u e}{3}} = \frac{12}{\textcolor{b l u e}{3}}$

Therefore,
$a = 4$

Hope this helps!
