Solution for 2-y/5y=4/15y-1/3 equation: 


y in (-oo:+oo)

2-((y/5)*y) = (4/15)*y-(1/3) // - (4/15)*y-(1/3)

1/3-((y/5)*y)-((4/15)*y)+2 = 0

(-1/5)*y^2+(-4/15)*y+1/3+2 = 0

7/3-1/5*y^2-4/15*y = 0

DELTA = (-4/15)^2-(-1/5*7/3*4)

DELTA = 436/225

DELTA > 0

y = ((436/225)^(1/2)+4/15)/(-1/5*2) or y = (4/15-(436/225)^(1/2))/(-1/5*2)

y = -5/2*((436/225)^(1/2)+4/15) or y = -5/2*(4/15-(436/225)^(1/2))

y in { -5/2*((436/225)^(1/2)+4/15), -5/2*(4/15-(436/225)^(1/2)) }
