x in (-oo:+oo)
(2/3)*(x/b+1) = (3/4)*(x/b-1) // - (3/4)*(x/b-1)
(2/3)*(x/b+1)-((3/4)*(x/b-1)) = 0
(2/3)*(x/b+1)+(-3/4)*(x/b-1) = 0
2/3*(b^-1*x+1)-3/4*(b^-1*x-1) = 0
2/3*(b^-1*x+1)-3/4*(b^-1*x-1) = 0
17/12-1/12*b^-1*x = 0
17/12-1/12*b^-1*x = 0
17/12-1/12*b^-1*x = 0 // - 17/12
-1/12*b^-1*x = -17/12 // : -1/12*b^-1
x = -17/12/(-1/12*b^-1)
x = 17*b
x = 17*b
