Activity #10:  Simplifying Algebraic expressions

Simplify the following expressions by combining like terms.

a.  5x - 5y + 2 + 2y + 4x - 5 = ________________
b. 4a + 6b - 5 - 10a - 6b + 4  = ________________
c. 3x² - 6x + 3 + 4x² + 4 + 1 = ________________
d. 3a² - 4 + 6a² - 6a - 2 + 2a² + a = ________________
e. 3x - 4 + 5x + 5 + 4 - 5x = ________________
f. 16a - 4a + 5 - 12a - 7 - 9 = ________________
g. 7f - 4f - 9f + 3 - 6 = ________________
h. 7p + 3 + 15p - 8 = ________________
i. 9h - 4h -4h + 5h = ________________
j. 5r - 5 + 3r = ________________
k. k + 5 + 3k + 6 + k = ________________
l. 9w - 6 + 5w - 12 = ________________
m. 14p - 5p + 3p - 4p = ________________
n. 3a + 5a + 7a - 4 + 6 - 10 = ________________
o. 3a² + 2b² - 3 + 7b² - 6 - a² + 10a² = ________________
p. -5x² + 3y² + 7 + 7y² - 3 - x² - 4y² = ________________

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

k= 2, p= 5, h= -5, r= 0, x= -6, y= 4, w= -5
