Question

urge porfavor ayuda ​

Answer 1

Explicación paso a paso:

para y

6x + y =17

2x + 5y =7 (-3)

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

6x + y =17

-6x -15y = -21

= 0 - 14y = -4

y = -4 /-14

y = 2/7

para x

6x + y =17 (-5)

2x + 5y =7

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

-30x -5y = - 85

2x +5y = 7

= -28x +0 = -78

-28x = -78

x = -78/-28

x = 39/14
