Activity #10:  Simplifying Algebraic expressions

                Part 1: Simplify the following expressions by combining like terms.

1.   5x - 5y + 2 + 2y + 4x - 5 = ________________
2.  4a + 6b - 5 - 10a - 6b + 4  = ________________
3.  3x² - 6x + 3 + 4x² + 4 + 1 = ________________
4.  3a² - 4 + 6a² - 6a - 2 + 2a² + a = ________________
5.  3x - 4 + 5x + 5 + 4 - 5x = ________________
6.  16a - 4a + 5 - 12a - 7 - 9 = ________________
7.  7f - 4f - 9f + 3 - 6 = ________________
8.  7p + 3 + 15p - 8 = ________________
9.  9h - 4h -4h + 5h = ________________
10.  5r - 5 + 3r = ________________

Part 2:  Evaluate the solutions from Part 1, when a = -2, b = -1, f = 4,

               p= 5, h= -5, r = 0, x= -6, y= 4
