    if x > 3 this is \[x-3+x-6=0\] \[2x=9\] \[x=\frac{9}{2}\] that is one answer

    if x <0 this is \[-x+3-x-6=0\] \[-2x=3\] \[x=-\frac{3}{2}\]

    and if 0 < x < 3 this is \[-x+3+x-6=0\] or \[-3=0\] so there is no solution on that intervals

    steps clear or not? you need to break up the absolute value into intervals where it is positive and negative. then get rid of absolute value signs and solve the linear equation
