x in (-oo:+oo)
3/2-((2*(x-9))/3)-6 = (1/6)*x // - (1/6)*x
3/2-((2*(x-9))/3)-((1/6)*x)-6 = 0
(-2/3)*(x-9)+(-1/6)*x+3/2-6 = 0
3/2-2/3*(x-9)-x/6-6 = 0
(-2/3*2*6*(x-9))/(2*6)+(2*(-x))/(2*6)+(3*6)/(2*6)+(-6*2*6)/(2*6) = 0
2*(-x)-2/3*2*6*(x-9)+3*6-6*2*6 = 0
18-10*x-72+72 = 0
90-10*x-72 = 0
18-10*x = 0
(18-10*x)/(2*6) = 0
(18-10*x)/(2*6) = 0 // * 2*6
18-10*x = 0
18-10*x = 0 // - 18
-10*x = -18 // : -10
x = -18/(-10)
x = 9/5
x = 9/5
