# What are the two ways to solve for x and get rid of the parentheses in 2(5x+9)=78?

Apr 10, 2018

Method 1: Distribute

Method 2: Divide both sides by two

$x = 6$

#### Explanation:

Method 1: Distribute

In the equation, you can just distribute like this:

$2 \left(5 x + 9\right) = 78 , 10 x + 18 = 78 , x = 6$

Method 2: Divide both sides by two

Another way is just to divide both sides of the equation like this:

$2 \left(5 x + 9\right) = 78 , 5 x + 9 = 39 , x = 6$

In both ways, you get $x = 6$
