____________

....….……..................

-62x+3y=1636
62x+3224y= - 92132
____________________
0 +3227y= - 90496
Buscamos valor de y
3227y= - 90496
Y= -90496/3227
Y= -12928/461
Y= - 28,04

Remplazamos valores
-62x+3y=1636
-62x+3(-12928/461)=1636
-62x+(-38784/461)=1636
-62x-38784/461=1636
-62x= 38784/461+1636
-62x= 38784+754196/461
-62x= 38784+754196/461
-62x= 792980/461
-x= 792980/461
__________
........ 62/1

-x= 792980/28582
X= - 792980/28582
X= 27,74
