1) 5x - 2y = 2 (6)
2) 7x + 6y = 38 (2)
30x - 12y = 12
14x + 12y = 76
-------------------
44x + 0y = 88
44x = 88
x = 88/44
x = 2
Reemplazo x = 2 en ecuación 1.
5x - 2y = 2
5 (2) - 2y = 2
10 - 2y = 2
- 2y = 2 - 10
- 2y = - 8
y = -8/-2
y = 4
Solución :
x = 2
y = 4
7x+6y=38
---------------
22x=44
X=2
5(2)-2y=2
10-2y=2
8=2y
Y=4
