1) 5x - 2y = 8 (-1)
2) x - 3y = 2 (5)
- 5x + 2y = - 8
5x - 15y = 10
---------------------
0x - 13y = 2
- 13y = 2
y = 2/-13
y = - 2/13
Sustituyo el valor de y en ecuación 2
x - 3y = 2
x - 3 (-2/13) = 2
x = 6/13 = 2
x = 2 - 6/13
x = (2 * 13 - 6)/13
x = (26 - 6)/13
x = 20/13
Solución :
x = 20/13
y = - 2/13
