y-19/y=-60

Solution for y-19/y=-60 equation:

D( y )

y = 0

y = 0

y = 0

y in (-oo:0) U (0:+oo)

y-(19/y) = -60 // + 60

y-(19/y)+60 = 0

y-19*y^-1+60 = 0

1*y^1-19*y^-1+60*y^0 = 0

(1*y^2+60*y^1-19*y^0)/(y^1) = 0 // * y^2

y^1*(1*y^2+60*y^1-19*y^0) = 0

y^1

y^2+60*y-19 = 0

y^2+60*y-19 = 0

DELTA = 60^2-(-19*1*4)

DELTA = 3676

DELTA > 0

y = (3676^(1/2)-60)/(1*2) or y = (-3676^(1/2)-60)/(1*2)

y = (2*919^(1/2)-60)/2 or y = (-2*919^(1/2)-60)/2

y in { (-2*919^(1/2)-60)/2, (2*919^(1/2)-60)/2} 

y in { (-2*919^(1/2)-60)/2, (2*919^(1/2)-60)/2 }
