4*x+7 = 0
4*x+7 = 0
4*x+7 = 0 // - 7
4*x = -7 // : 4
x = -7/4
x in (-oo:-7/4) U (-7/4:+oo)
(5*x-4)/(4*x+7) = 13/11 // - 13/11
(5*x-4)/(4*x+7)-(13/11) = 0
(5*x-4)/(4*x+7)-13/11 = 0
(11*(5*x-4))/(11*(4*x+7))+(-13*(4*x+7))/(11*(4*x+7)) = 0
11*(5*x-4)-13*(4*x+7) = 0
3*x-135 = 0
(3*x-135)/(11*(4*x+7)) = 0
(3*x-135)/(11*(4*x+7)) = 0 // * 11*(4*x+7)
3*x-135 = 0
3*x-135 = 0 // + 135
3*x = 135 // : 3
x = 135/3
