How do I solve equations with varibables on both sides of it?

I'll give you an example:

$4x - 4 = x-7$

Make sure all the terms with x are on the same side. To do that, subtract x from both sides, and you get:

$4x - 4-x = x-7-x$

$3x - 4 =-7$

Now add 4 to both side to give:

$3x -4 +4= -7+4$

$3x = -3$

Now, divide both sides by 3 to give:

$\frac{3x}{3} = \frac{-3}{3}$

$x = -1$

See?
