Answer 1

Your answer would be (-6,-8)

Answer 2

x=-6, y=-8. (-6, -8).

Explanation:

8x-5y=-8

-7x-5y=82

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

-(8x-5y)=-(-8)

-7x-5y=82

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

-8x+5y=8

-7x-5y=82

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

-15x=90

x=90/-15

x=-6

8(-6)-5y=-8

-48-5y=-8

5y=-48-(-8)

5y=-48+8

5y=-40

y=-40/5

y=-8
