Exercise 5 Page 210

Recall the Distributive Property.

4x-3.4yx

Practice makes perfect

We want to simplify the given expression. To do it, we will use the Distributive Property. We will distribute x to the terms inside the parentheses.

x(4-3.4y)

Distribute x

x(4)-x(3.4y)

CommutativePropMult

Commutative Property of Multiplication

(4)x-(3.4y)x

Remove parentheses

4x-3.4yx

Since 4x and 3.4yx are not like terms, the expression cannot be simplified further.
