Answer:

(-4,5)

*View attached graph*

Step-by-step explanation:

y = -2x - 3

4y + x = 16

4y + x = 16

4(-2x - 3) + x = 16

-8x - 12 + x = 16

-7x - 12 = 16

     +12   + 12

-7x = 28

/-7    /-7

x = -4

4y + x = 16

4y + (-4) = 16

4y - 4 = 16

   + 4   + 4

4y = 20

/4     /4

y = 5

(x,y) -> (-4,5)

Hope this helps!
