Answer:

a = 5

Step-by-step explanation:

3(a+3)+6=30

Subtract 6 from each side

3(a+3)+6-6=30-6

3(a+3) = 24

Divide by 3

3/3(a+3) = 24/3

a+3 = 8

Subtract 3 from each side

a+3-3 = 8-3

a = 5

Answer:

a = 5

Step-by-step explanation:

  1. Apply the distributed property, so it now looks like this: 3a + 9 + 6 = 30
  2. Simplify: 3a + 15 = 30
  3. Subtract 15 from each side, so it now looks like this: 3a = 15
  4. Divide each side by 3 to cancel out the 3 next to a. It should now look like this: a = 5

I hope this helps!
