Question

I need help !!!!!!!!!!!

Answer 1

1. For the first equation put in 4
2. For the second equation put in -12

(See below for writing)

Explanation:

1. when you distribute 3 you multiply by three, so you have to do the opposite to find your answer.12/3=4

2. You just have to rewrite it. If you made the second one a positive equation, you would have 3x+ (-12).

For the writing part,

You could use the distributive property to simplify the equation and make it easier to solve for x.
