Question

–4x + 7 = x + 2
how do I do this

Answer 1

Okay so basically what you have to do is isolate the variable, which is x, in this case.

Answer 2

You can do this by moving -4x to the right side, make it positive, so it will be 7 = x + 4x +2, which we can simplify to be 7= 5x +2.
Now that we have this, we will continue isolating.
we move the 2 on the right side to the left, and making it negative:
so it will be 7-2 = 5x. We finally get 5 = 5x. We divide both sides by x, to get 1 = x.
