4/(5*x+2) = 6/(x-1) // - 6/(x-1)
4/(5*x+2)-(6/(x-1)) = 0
4/(5*x+2)-6*(x-1)^-1 = 0
4/(5*x+2)-6/(x-1) = 0
(4*(x-1))/((5*x+2)*(x-1))+(-6*(5*x+2))/((5*x+2)*(x-1)) = 0
4*(x-1)-6*(5*x+2) = 0
(4-30)*x-12-4 = 0
((4-30)*x-12-4)/((5*x+2)*(x-1)) = 0
((4-30)*x-12-4)/((5*x+2)*(x-1)) = 0 // * (5*x+2)*(x-1)
(4-30)*x-12-4 = 0
(4-30)*x-12-4 = 0 // + -12-4
(4-30)*x = -(-12-4) // : 4-30
x = (-(-12-4))/(4-30)
x = (4+12)/(4-30)
x = (4+12)/(4-30)
