z in (-oo:+oo)
3-((5/4)*(2*z-6)) = 5*z-(2/3) // - 5*z-(2/3)
2/3-((5/4)*(2*z-6))-(5*z)+3 = 0
(-5/4)*(2*z-6)-5*z+2/3+3 = 0
2/3-5/4*(2*z-6)-5*z+3 = 0
(-5/4*3*(2*z-6))/3+(-5*3*z)/3+2/3+(3^2)/3 = 0
2-5/4*3*(2*z-6)-5*3*z+9 = 0
2-45/2*z+9+45/2 = 0
9-45/2*z+49/2 = 0
67/2-45/2*z = 0
(67/2-45/2*z)/3 = 0
(67/2-45/2*z)/3 = 0 // * 3
67/2-45/2*z = 0
67/2-45/2*z = 0 // - 67/2
-45/2*z = -67/2 // : -45/2
z = -67/2/(-45/2)
z = 67/45
z = 67/45
