# How do you solve 2x+8.5=20.4?

Oct 18, 2017

$x = 5.95$

#### Explanation:

Subtract $8.5$ from both sides of the equation so you can remove it.

$2 x + \cancel{8.5} = 20.4 - 8.5$
$2 x = 11.9$

Divide both sides of the equation by $2$ so you can solve for $x$.

$\frac{2 x}{2} = \frac{11.9}{2}$

$\therefore x = 5.95$
