Answer:

(-7,5)

Explanation:

8x = -46 - 2y

2y = -46 - 8x

7x = -59 + 2y

7x = -59 - 46 - 8x

15x = -105

x = -7

2y = -46 - 8(-7) = 10

y = 5

Answer:

x = -7, y =5

Explanation:

8x = -46 - 2y

7x = -59 + 2y

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

Add the two equations together to eliminate y

8x = -46 - 2y

7x = -59 + 2y

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

15x =-105

Divide each side by 15

15x/15 = -105/15

x =-7

Now solve for y

7x = -59+2y

7(-7) = -59+2y

-49 = -59+2y

Add 59 to each isde

-49+59 = 2y

10 = 2y

Divide each side by 2

10/2 = 2y/2

5 =y
