Solución detallada
Tenemos una ecuación lineal:
2*y^2-5*sqrt(2)*x+5*sqrt(2)*y = 0
Abrimos los paréntesis en el miembro izquierdo de la ecuación
2*y^2-5*sqrt2x+5*sqrt2y = 0
Dividamos ambos miembros de la ecuación en (2*y^2 - 5*x*sqrt(2) + 5*y*sqrt(2))/x
x = 0 / ((2*y^2 - 5*x*sqrt(2) + 5*y*sqrt(2))/x)
Obtenemos la respuesta: x = y*(5 + y*sqrt(2))/5
