x in (-oo:+oo)
(1/2)*(6*x+4) = (2/3)*(x+9)+(1/3)*x // - (2/3)*(x+9)+(1/3)*x
(1/2)*(6*x+4)-((2/3)*(x+9))-((1/3)*x) = 0
(1/2)*(6*x+4)+(-2/3)*(x+9)+(-1/3)*x = 0
1/2*(6*x+4)-2/3*(x+9)-x/3 = 0
(1/2*3*(6*x+4))/3+(-2/3*3*(x+9))/3-x/3 = 0
1/2*3*(6*x+4)-2/3*3*(x+9)-x = 0
7*x-x-12 = 0
6*x-12 = 0
(6*x-12)/3 = 0
(6*x-12)/3 = 0 // * 3
6*x-12 = 0
6*x-12 = 0 // + 12
6*x = 12 // : 6
x = 12/6
