x in (-oo:+oo)
(2*x+1)/3 = (5*x-4)/11 // - (5*x-4)/11
(2*x+1)/3-((5*x-4)/11) = 0
(2*x+1)/3+(-1*(5*x-4))/11 = 0
(11*(2*x+1))/(3*11)+(-1*3*(5*x-4))/(3*11) = 0
11*(2*x+1)-1*3*(5*x-4) = 0
7*x+23 = 0
(7*x+23)/(3*11) = 0
(7*x+23)/(3*11) = 0 // * 3*11
7*x+23 = 0
7*x+23 = 0 // - 23
7*x = -23 // : 7
x = -23/7
x = -23/7
