1 answer:
Misha Larkins [42]4 years ago
5 0

Answer:

x=-4, y=2. (-4, 2).

Step-by-step explanation:

5x+6y=-8

-2x+8y=24

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

2(5x+6y)=2(-8)

5(-2x+8y)=5(24)

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

10x+12y=-16

-10x+40y=120

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

52y=104

y=104/52

y=2

5x+6(2)=-8

5x+12=-8

5x=-8-12

5x=-20

x=-20/5

x=-4
