Solution for (9x/4x)-(85/4x)=(-9/4x) equation: 


x in (-oo:+oo)

((9*x)/4)*x-((85/4)*x) = (-9/4)*x // - (-9/4)*x

((9*x)/4)*x-((85/4)*x)-((-9/4)*x) = 0

((9*x)/4)*x+(-85/4)*x+(9/4)*x = 0

9/4*x^2-19*x = 0

DELTA = (-19)^2-(0*9/4*4)

DELTA = 361

DELTA > 0

x = (361^(1/2)+19)/(2*9/4) or x = (19-361^(1/2))/(2*9/4)

x = 76/9 or x = 0

x in { 0, 76/9 }
