# How do you solve for y: in  3y = ab?

color(hotpink)("y = (ab)/3

#### Explanation:

Let's divide both sides by three to get $y$ by itself:

$\frac{\cancel{\text{3}} y}{\cancel{3}} = \frac{a b}{3}$

Dividing by the same number (three in our case) gives you one on the left side so you are just left with $y$:

$y = \frac{a b}{3}$
