Primer Forma:
22x+17y = 49 (1/17) = 22/17x+y = 49/17
31x-26y = 119 (1/26) = 31/26x-y = 119/26
22/17x+y = 49/17
31/26x-y = 119/26
______________
1099/442x = 3297/442
x = 329/442.442/1099
x = 3
*Reemplazamos para hallar el valor de Y
22x+17y = 49
22.3+17y = 49
66+17y = 49
17y = 49-66
17y = -17
y = -17/17
y = -1
Segunda Forma:
22x+17y = 49 (1/22) = x+17/22y = 49/22
31x-26y = 119 (-1/31) = -x+26/31y = -119/31
x+17/22y = 49/22
-x+26/31y = -119/31
_______________
1099/682y = -1099/682
y = -1099/682.682/1099
Y = -1
* Para Hallar X
22x+17y = 49
22x+17.(-1) = 49
22x = 49+17
22x = 66
x = 3
