(1/8)*(5*x+3)-x = (1/3)*(8*x-6)+19/8 // - (1/3)*(8*x-6)+19/8
(1/8)*(5*x+3)-((1/3)*(8*x-6))-x-(19/8) = 0
(1/8)*(5*x+3)+(-1/3)*(8*x-6)-x-19/8 = 0
1/8*(5*x+3)-1/3*(8*x-6)-x-19/8 = 0
(1/8*8*(5*x+3))/8+(-1/3*8*(8*x-6))/8+(8*(-x))/8-19/8 = 0
1/8*8*(5*x+3)-1/3*8*(8*x-6)+8*(-x)-19 = 0
19-49/3*x-8*x-19 = 0
19-73/3*x-19 = 0
-73/3*x = 0
(-73/3*x)/8 = 0
(-73/3*x)/8 = 0 // * 8
(-73*x)/3 = 0
-73/3*x = 0 // : -73/3
