Answer:

a = 5

Explanation:

3 (a + 3) + 6 = 30

Use the distibutive property to multiply 3 by a + 3

3a + 9 + 6 = 30

Add 9 and 6 to get 15

3a + 15 = 30

Subtract 15 from both sides

3a = 30 - 15

Subtract 15 from 30 to get 15.

3a = 15

Divide both sides by 3.

a = 15/3

Divide 15 by 3 to get 5

a = 5
