Question

ME PUEDEN AYUDAR
10X – 3Y = 125
3X + 4Y = 13

Answer 1

Claro amigo ^^.

=> 10x-3y=125
10x=125+3y
x= (125+3y)/10

=> 3x+4y=13
3x=13-4y
x=(13-4y)/3

Igualamos las "x" :

(125+3y)/10 = (13-4y)/3
3(125+3y) = 10(13-4y)
375+9y = 130 -40y
49y = -245
y = -5

Hallamos "x" :
x= (125+3(-5))/10
x= (125-15)/10
x= 110/10
x= 11

Espero te sirva !!!
