Question:

Solve 3a + 6a + 2 = 8a + 20 - 5a

Steps:

1. Simplify, 3a + 6a: 9a , 8a - 5a: 3a

  • 9a + 2 = 3a + 20

2. Then, subtract 2 from both sides

  • 9a + 2 - 2 = 3a + 20 - 2

3. Simplify,

  • 9a = 3a + 18

4. Then, subtract 3a from both sides

  • 9a - 3a = 3a - 3a + 18

5. Simplify,

  • 6a = 18

6. Then, divide both sides by 6

  • 6a/6 = 18/6

7. Simplify,

  • a = 3 is the answer!

Hope that helped!
