Question

ayuda
4x+y = 6
9x + 7y=50​

Answer 1

Respuesta:

4x+y = 6

9x + 7y=50​

-28 - 7y= - 42

9x+7y= 50

----------------------

-19x_0= 8

X= - 8/19.

4x+y= 6

4(-8/19) + y= 6

-32/19 +y= 6

Y= 6 +32/19

Y=114/19 +32/19

Y= 146/19

Comprobamos

4x+y= 6

4(-8/19) + 146/19= 6

-32/19 +146/19= 6

114/19= 6

6= 6.
