anonymous one year ago PLEASE HELP ME UNDERSTAND!:) Solve 7x − 2(x + 1) = 6x + 14. −12 12 −16 16

1. anonymous

We are trying to isolate the x variable.

2. anonymous

In order to do that, we need to move everything onto one side of the equation so x is by itself.

3. anonymous

Now, we must follow PEMDAS also. Do you know how to distribute?
