Question

How would I solve 3(4m- 7) + 7

Answer 1

We have to solve:

`3(4m-7)+7`

First we need to distribute the product using the distributive property of the multiplication:

`a\cdot(b+c)=ab+ac`

Using this property we get:

`3(4m-7)+7=3\cdot4m-3\cdot7+7=12m-21+7=12m-14`

Then the answer is 12m-14.
