Answer:

x=-1, y= -6

Step-by-step explanation:

4x+y=-10

9x+y=-15

Subtract the second equation

4x+y=-10

-9x-y=15

---------------------

-5x    = 5

Divide each side by -5

-5x/-5 = 5/-5

x = -1

Now find y

4x+y = -10

4(-1) +y = -10

-4+y = -10

Add 4 to each side

-4+4 +y = -10+4

y = -6

Answer:

(-1,-6)

Step-by-step explanation:

y = -10-4x

y = -15-9x

-10-4x = -15-9x

5x = -5

x = -1

y = -15-(-9) = -6
