Practice Problems

Practice identifying which property of real numbers is demonstrated in the Lesson 2 Property Identification Practice Quiz

Combine like terms to completely simplify each of the following:

7. 8x + 3x − 5x

8. 6x + 7y − 8x + 9y

9. 9x − 3x + 6 − 9

Remove the grouping symbols and combine like terms to completely simplify the following:

10. (8x − 3) − (2x + 5)

11. (7x + 5) − (4x − 6)

12. −(3x − 2) + (8x − 7)

13. (5x + 2y − 7) − (3x − 2y − 9)

Use order of operations to simplify each of the following:
