- 4. How Many? x + 2x -x + -2x x - 2x -x - -2x
- 5. Combine Terms 7x – 5y – 4x + 3y 7x – 5y – 4x + 3y 3x – 2y
- 6. Combine Terms 2c – 3 + 9d + 7 - 6d 2c – 3 + 9d + 7 - 6d 2c + 4 + 3d
- 7. Combine Terms 7 – 5c – d + 9c + 2 7 – 5c – d + 9c + 2 9 + 4c – d
- 8. Combine Terms & Solve 2n + 3n +7 = -41 5n +7 = -41 5n = -48 n = -48/5
- 9. Combine Terms & Solve 3h – 5h + 11 = 17 -2h + 11 = 17 -2h = 6 h = -3
