x in (-oo:+oo)
(2/3)*(x+4)-((3/4)*(2*x+5)) = (1/12)*(x-2) // - (1/12)*(x-2)
(2/3)*(x+4)-((3/4)*(2*x+5))-((1/12)*(x-2)) = 0
(2/3)*(x+4)+(-3/4)*(2*x+5)+(-1/12)*(x-2) = 0
2/3*(x+4)-3/4*(2*x+5)-1/12*(x-2) = 0
2/3*(x+4)-3/4*(2*x+5)-1/12*(x-2) = 0
1/6-5/6*x-1/12*x-13/12 = 0
-11/12*x-11/12 = 0
-11/12*x-11/12 = 0
-11/12*x-11/12 = 0 // + 11/12
-11/12*x = 11/12 // : -11/12
x = 11/12/(-11/12)
x = -1
x = -1
