x in (-oo:+oo)
(5/12)*x-((3/4)*(x-3)) = (1/6)*(2*x-7) // - (1/6)*(2*x-7)
(5/12)*x-((3/4)*(x-3))-((1/6)*(2*x-7)) = 0
(-3/4)*(x-3)+(-1/6)*(2*x-7)+(5/12)*x = 0
(5*x)/12-3/4*(x-3)-1/6*(2*x-7) = 0
(-3/4*12*(x-3))/12+(-1/6*12*(2*x-7))/12+(5*x)/12 = 0
5*x-3/4*12*(x-3)-1/6*12*(2*x-7) = 0
5*x-13*x+41 = 0
41-8*x = 0
(41-8*x)/12 = 0
(41-8*x)/12 = 0 // * 12
41-8*x = 0
41-8*x = 0 // - 41
-8*x = -41 // : -8
x = -41/(-8)
x = 41/8
x = 41/8
