   2       ___         ___      
2*y  - 5*\/ 2 *x + 5*\/ 2 *y = 0
$$5 \sqrt{2} y + \left(- 5 \sqrt{2} x + 2 y^{2}\right) = 0$$
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
