Ha introducido [src]
2*x*y = 3*(x - 5)*(y - 2)
$$2 x y = 3 \left(x - 5\right) \left(y - 2\right)$$
Solución detallada
Tenemos la ecuación:
2*x*y = 3*(x-5)*(y-2)

Abrimos la expresión:
2*x*y = 30 - 15*y - 6*x + 3*x*y

Reducimos, obtenemos:
-30 + 6*x + 15*y - x*y = 0

Transportamos los términos libres (sin x)
del miembro izquierdo al derecho, obtenemos:
$$- x y + 6 x + 15 y = 30$$
Move the summands with the other variables
del miembro izquierdo al derecho, obtenemos:
$$- x y + 6 x = \left(-15\right) y + 30$$
Dividamos ambos miembros de la ecuación en (6*x - x*y)/x
x = 30 - 15*y / ((6*x - x*y)/x)

Obtenemos la respuesta: x = 15*(-2 + y)/(-6 + y)
