Simplify each expression by combining like terms. 1. 8a – 5a 2. 12g + 7g 3. 4a + 7a + 6 4. 6x + 3y + 5x 5. 10k + 5w – 3k 6. 3p – 7n + 14p – 5 7. 4(x + 3) – 5 8. 6(7 + x) + 5x 9. 3(5 + 3x) – 4x 12. 8 – 2(w – 4) 10. 10 – 3(x + 2) 11. 7 + 4(y – 3) 13. 4x2 + 3x + 5x 2 14. 7xy – 3x + 5y + 2xy – 4x 15. 8w3 – 3w2 + w – 5 + 2w 2 + 9 16. 5x – 3 + 5(x – 4) + 2 1.6 Day 2 More practice combining like terms Solve each equation, showing all work. Remember to combine like terms first! 17. 6y + 2y = 16 19. 3x + 8 + 5x = 48 18. 14x + 3 – 9x = 38 20. 4(g + 7) = 64 22. Consecutive integers are integers that differ by one. You can represent consecutive integers as x, x + 1, x + 2, and so on. Write an equation and solve to find three consecutive integers whose sum is 33.
