# How do you solve 4x=20?

Mar 2, 2018

$x = 5$

#### Explanation:

$4 x = 20$

For solving for x , you need to isolate it.

Here, x is multiplied by 4. So divide both sides by 4.

$\implies \frac{4 x}{4} = \frac{20}{4}$

$\implies \frac{\cancel{4} x}{\cancel{4}} = \frac{{\cancel{20}}^{5}}{\cancel{4}}$

$\implies x = 5$
