Question

AYUDA!!!!!!!!!!!!!!

metodo de reduccion
4m+n=6
-2m+2n=2

Answer 1

1) 4m + n = 6        (2)
2) - 2m + 2n = 2    (4)

8m + 2n = 12
-8m + 8n = 8
------------------
0m + 10m = 20

10m = 20

m = 20/10

m = 2

Reemplazo en 1.

4m + n = 6

4 (2) + n = 6

8 + n = 6

n = 6 - 8

n = - 2

Solución : 

m = 2
n = - 2
