1) 5m - 2n = 13
2) m + 3n = 6
Despejo m en ecuación 2
m + 3n = 6
m = 6 - 3n
Sustituyo el despeje de m en ecuación 1
5m - 2n = 13
5 (6 - 3n) - 2n = 13
30 - 15n - 2n = 13
30 - 17n = 13
- 17n = 13 - 30
- 17n = - 17
n = -17/-17
n = 1
El valor de n lo sustituyo en el despeje de m
m = 6 - 3n
m = 6 - 3 (1)
m = 6 - 3
m = 3
Respuesta
m = 3
n = 1
