Answer:

x=12/17, y=59/34. (12/17, 59/34).

Explanation:

5x+2y=7

-2x+6y=9

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

-3(5x+2y)=-3(7)

-2x+6y=9

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

-15x-6y=-21

-2x+6y=9

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

-17x=-12

17x=12

x=12/17

5(12/17)+2y=7

60/17+2y=7

2y=7-60/17

2y=119/17-60/17

2y=59/17

y=(59/17)/2

y=(59/17)(1/2)

y=59/34
