(3*y-2)/(y+1) = 4-((y+2)/(y-1)) // - 4-((y+2)/(y-1))
(3*y-2)/(y+1)+(y+2)/(y-1)-4 = 0
((3*y-2)*(y-1))/((y+1)*(y-1))+((y+2)*(y+1))/((y+1)*(y-1))+(-4*(y+1)*(y-1))/((y+1)*(y-1)) = 0
(3*y-2)*(y-1)+(y+2)*(y+1)-4*(y+1)*(y-1) = 0
4*y^2-4*y^2-2*y+4+4 = 0
8-2*y = 0
(8-2*y)/((y+1)*(y-1)) = 0
(8-2*y)/((y+1)*(y-1)) = 0 // * (y+1)*(y-1)
8-2*y = 0
8-2*y = 0 // - 8
-2*y = -8 // : -2
y = -8/(-2)
