(1/6)*(8*x-13)-(2/3) = (5/6)*(x+2) // - (5/6)*(x+2)
(1/6)*(8*x-13)-((5/6)*(x+2))-(2/3) = 0
(1/6)*(8*x-13)+(-5/6)*(x+2)-2/3 = 0
1/6*(8*x-13)-5/6*(x+2)-2/3 = 0
(1/6*3*(8*x-13))/3+(-5/6*3*(x+2))/3-2/3 = 0
1/6*3*(8*x-13)-5/6*3*(x+2)-2 = 0
3/2*x-23/2-2 = 0
3/2*x-27/2 = 0
(3/2*x-27/2)/3 = 0
(3/2*x-27/2)/3 = 0 // * 3
3/2*x-27/2 = 0
3/2*x-27/2 = 0 // + 27/2
3/2*x = 27/2 // : 3/2
x = 27/2/3/2
x = 9
