Instructions:

Simplify each expression by collecting like terms. Remember: like terms have the same variable part.

Section A: Two Variables

1. 3x + 5y + 2x + y = _________________________
2. 7a + 4b - 3a + 2b = _________________________
3. 5m - 2n + 3m + 6n = _________________________
4. 8p + 3q - 5p - q = _________________________
5. 6x - 4y - 2x + 7y = _________________________

Section B: With Constants

6. 4x + 7 + 2x - 3 = _________________________
7. 5a - 2 + 3a + 8 = _________________________
8. 9y + 4 - 3y - 1 = _________________________
9. 2m + 5n + 6 + 3m - n - 4 = _________________________
10. 7p - 3q + 9 - 2p + 5q - 6 = _________________________

Section C: Multiple Variables

11. 3x + 2y + 5z + x - 3y + 2z = _________________________
12. 6a - 4b + 2c - a + 5b - c = _________________________
13. 5m + 3n - 2p + 4m - n + 6p = _________________________
14. 8x - 3y + 7 + 2x + 5y - 4 - x = _________________________
15. 4a + 6b - 2c + 10 - 3a - b + 5c - 7 = _________________________
