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`
