I completed this problem but I am not sure if it goes like this.

3x-6=-3(2-x) problem

My answer

3x-6=-6-x
3x+x=-6+6

4x=0

You made some mistakes here when multiplying the brackets, the left and right sides are the same:

3x-6 = -3(2-x) \\
3x-6 = -6+3x (you see here that -3*-x = +3x, whereas you had it as -x)
3x-6 = 3x-6

since both left and right sides are the same, any x will solve the equation.

Is it possible that you made some mistakes before this?

Thank you very much. I get confused sometimes. I get what you are saying and re-worked the program. Great help!!
