ok so basically, you are going to use the distributive property to solve this problem.

First, Use the distributive property.

So basically 3(x + 4) = 9 would be:

3x + 12 = 9 after the distributive property

Then you subtract 12 from both sides

3x = -3

Then you divide 3 by both sides

you will get x = -1

Hope this helps
