  6. Find the value of x.

  7. What is x = 17?

  8. Find the value of x.

  9. What is x = 10? 2(3x) = 4x + 20 6x = 4x + 20 2x = 20 x = 10

  10. Find the value of x.

  11. What is x = 3? 2(2x) = x + 9 4x = x + 9 3x = 9 x = 3

  12. Find the value of x.

  13. What is x = 4? 4x = 3x + 4 x = 4

  14. Find the values of AB and BC.

  15. What is AB = 16 and BC = 16? 4x = 3x + 4 x = 4 AB = 4(4) = 16 BC = 4(3) + 4 = 16
