Exercise 39 Page 15

We will begin simplifying by distributing

4

and

8

to the terms inside the parentheses.

4 (4 x - 9 y) + 8 (3 x + 2 y)

Distribute $4$

16 x - 36 y + 8 (3 x + 2 y)

Distribute $8$

16 x - 36 y + 24 x + 16 y

CommutativePropAdd

Commutative Property of Addition

16 x + 24 x - 36 y + 16 y

Add and subtract terms

40 x - 20 y

Since

40 x

and

- 20 y

are not like terms, the expression cannot be simplified further.
