y in (-oo:+oo)
26/5 = 9*y-((2/5)*(8*y-3)) // - 9*y-((2/5)*(8*y-3))
(2/5)*(8*y-3)-(9*y)+26/5 = 0
(2/5)*(8*y-3)-9*y+26/5 = 0
2/5*(8*y-3)-9*y+26/5 = 0
(2/5*5*(8*y-3))/5+(-9*5*y)/5+26/5 = 0
2/5*5*(8*y-3)-9*5*y+26 = 0
26-29*y-6 = 0
20-29*y = 0
(20-29*y)/5 = 0
(20-29*y)/5 = 0 // * 5
20-29*y = 0
20-29*y = 0 // - 20
-29*y = -20 // : -29
y = -20/(-29)
y = 20/29
y = 20/29
