Answer:

x=.5, y=-5.5

Step-by-step explanation:

7x+y=5, 7x+y=-2

Simplifing 7x+y=5 first

7x+y=5

y=-7x+5

Next, 7x+y=-2

7x+y=-2

y=-7x-2

Plugging in -7x+5 into y

-7x+5=-7x-2

-14x=-7

x=.5

Plugging .5 into y=-7x-2

y=-7(.5)-2

y=-3.5-2

y=-5.5

I used substitution if your couldn't tell

Hope it helps!
