Use algebra tiles to simplify each expression. ( I need to turn this in before tommorow because thats when the quarter ends I would really appreciate it thanks :) )
7. 3 + 5x – 4 – 7x 8. –x – 4x – 7 9. –(–x + 3)
10. 4x – (x + 2) 11. 5x – (–3x + 2) 12. x – 5 – (2 – x)
13. 1 – 2y – 2y 14. –3x + 5 + 5x – 1 15. 3 – (y + 5)
16. –(x + y) + 4x + 2y 17. 3x – 7 – (3x – 7) 18. –(x + 2y + 3) – 3x + y
