Question

The Following steps are used to rewrite the polynomial expression 3(x+4y) + 5(2x-y)

Identify the properties used in each of the steps

Answer 1

Let's solve this problem step by step.

1. First of all we have this equation:

$3(x + 4y) + 5(2x - y)$

2. Let's apply distributive property:

$3x+12y + 10x - 5y$

3. Let's order this expression according to the variables:

$3x + 10x + 12y-5y$

4. Let's sum equal terms:

$13x + 7y$
