Answer:
y is equal to -1
x is equal to 4
Step-by-step explanation:
The first thing you would do is multiply the bottom equation by a negative 3. You will get - 6x - 9y = -15. Keep the top equation the same. Both of the 6x's cancel. You then get -11y = 11 so y is equal to negative 1.
Since you have Y, you can now plug that in to any equation to find the value of x. -6x - 2(-1) = 26. You're left with 4. Plug both of the values into each equation to double check.

Omg you need to find the quadrant 1,2,3,4 then once you doo you can put your number
Answer:
(x - 2)² + (y + 8)² = 121
Step-by-step explanation:
circle: (x – h)² + (y – k)² = r² (h , k) center r: radius
h = 2 k = - 8 r = 11
equation: (x - 2)² + (y + 8)² = 121
