First step is to have only one variable since they are both the same.
For example, the 5x will turn into -5x to be added on each side.
5x -4 = 4x
-5x. -5x
This will turn into -4 = -x
However, you can’t have a negative variable.
So you divide both sides by -1.
-4/-1 = -x/-1
4 = x
Switch the variable and the answer which the answer is: x = 4
