Debemos eliminar una de las variables
Procedemos asi
5X + 2Y = 20 (1)
3X + 8Y = 34 (2)
Multiplicando (1) x (- 4)
- 20X - 8Y = - 80 (3)
Sumando (20 + (3)
- 17X = 46
X = 46/- 17) = - 46/17
X en (1) [si prefieres puedes usar (2) o (3)]
5(- 46/17) + 2y = 20
- 230/17 + 2y = 20
2y = 20 + 230/17
2y = 340/17 + 230/17
2y = 570
y = 570/2
y = 285
Solución
X = - 46/17
Y = 285
