Answer:

x=15

Explanation:

First, distribute into the parenthesis by 1 to get rid of the parenthesis.

The 1 is also called an "invisible one" to distribute into parenthesis.

3x+8x+15= 180

Now, add the common variables.

11x+15= 180

Subtract to both sides by 15.

11x+15= 180

-15 -15

Now divide both sides by 11 to isolate the variable.

11x= 165

11 11

x= 15
