Answer:

x = -2 and y = -4

Step-by-step explanation:

Given:

2x + y = -8

x - y = 2

Add the two equations:

3x + 0y = -6

3x = -6

x = -2

Sub x = -2 into the second equation

-2 - y = 2

-4 = y

Therefore, x = -2 and y = -4

Helen [10]

Answer:

y = 6

Step-by-step explanation:

\sqrt{(10-3)^2 + (y+18)^2} = 25 \\ 49 + y^2 + 324 + 36y = 625 \\

y^2 + 36y - 252 = 0

(y-6)(y+42) = 0

y = 6 (accettable)

y = -42 (not accettable)
