- 2x + 3y = 18 - 5y + x = - 23 me ayudan x3 : v.
En resumen
- 2x + 3y = 18 - 5y + x = 23 / - 2 - 2x + 3y = 18 - 10y - 2x = 46 - 7y = - 28 y = 4 2x + 3 x 4 = 18 2x + 12 = 18 - 12 2x = 6x x = 3 Respuesta = (3, 4).
Mejor respuesta
- 2x + 3y = 18 - 5y + x = 23 / - 2 - 2x + 3y = 18 - 10y - 2x = 46 - 7y = - 28
y = 4
2x + 3 x 4 = 18
2x + 12 = 18 - 12
2x = 6x
x = 3
Respuesta = (3, 4).
