how do I do this problem
3x-3=x-4
Answered by Marcos
you want to get x all by its self.

subtract the x from both sides to give

2x-3=-4

add 3 to both sides

2x=-1

divide by 2 to isolate the x

x = -1/2

I still don't understand how you got the 2x?
Answered by Ms. Sue
As he said, he subtracted x from both sides of the equation.
3x - x = 2x
