Answer:

a = 15

Explanation:

8a + 2a + a + 15 = 180

What is the value of a?

___________________

To solve this, we first need to do everything to get "a" alone.

8a + 2a + a + 15 = 180

Add like terms :

8a + 2a + a

11a

11a + 15 = 180

Subtract 15 from both sides :

11a = 165

Divide 11 from both sides to get "a" alone :

a = 15
