Answer:

x = -2 and y = -5

Step-by-step explanation:

5x - y = -5

5x + 5 = y

Now , Substituting value of y in 3x-6y = 24

3x - 6(5x + 5) =24

3x - 30x -30 = 24

-27 x - 30 = 24

-30 - 24 = 27x

-54 =27x

x = -54/27

x = -2

Substituting value of x in 5x-y=-5

5 (-2) - y = -5

-10 -y =-5

-10 +5 =y

y = -5
