Answer:
x = -7, y =5
Step-by-step 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
Answer:
(-7,5)
Step-by-step 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
