y = -5
5x + 4y = -20

    5x + 4y = -20
5x + 4(-5) = -20
    5x - 20 = -20
        + 20  + 20
           5x = 0
            5     5
             x = 0
       (x, y) = (0, -5)
Y=-5
5x+4y=-20

Substitute y into the equation. 

5x + 4(-5) = -20
5x + -20  = -20
        +20    +20

5x = 0
x = 0

Now we have our values. 

Answer: y = -5 and x = 0
