x in (-oo:+oo)
3-((2*x-3)/4) = (8*x-11)/12 // - (8*x-11)/12
3-((2*x-3)/4)-((8*x-11)/12) = 0
(-1*(2*x-3))/4+(-1*(8*x-11))/12+3 = 0
(-1*12*(2*x-3))/(4*12)+(-1*4*(8*x-11))/(4*12)+(3*4*12)/(4*12) = 0
3*4*12-1*12*(2*x-3)-1*4*(8*x-11) = 0
80-56*x+144 = 0
224-56*x = 0
(224-56*x)/(4*12) = 0
(224-56*x)/(4*12) = 0 // * 4*12
224-56*x = 0
224-56*x = 0 // - 224
-56*x = -224 // : -56
x = -224/(-56)
x = 4
x = 4
