Answer:

Explanation:

5) a) x + 2x +3x = 6x

b) 2a - 1 + a +1 + 2a-1 + a + 1 = 6a

c) 1 + b + 2b + b + (2b + 1) + 2b = 8b + 2

d) 2 + y + 3y -2 + y + 2 + 3y -2 = 8y

6) 5ba² + 2x + 1 + 4ba² - 8 - x -x = 9ba² + 2x +1 - 8 -x -x

=9ba² +2x -2x + 1 - 8 = 9ba² + 0 -7 = 9ba² - 7

-ba² + 5 + 10ba² - 12 = 9ba² - 7
