    Interval Notation in Solution Sets-Tricky One
    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:

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


    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?
