Answer:
x=5 y=-1
Step-by-step explanation:
y=-5x+24
y=4x-21
Since both equations are equal to y, we can set them equal to each other
-5x+24=4x-21
Add 5x to each side
-5x+5x+24=4x+5x-21
24 = 9x-21
Add 21 to each side
24+21 = 9x-21+21
45 = 9x
Divide by 9
45/9 = 9x/9
5 =x
Now we need to find y
y = 4x-21
y =4(5) -21
y =20-21
y =-1

Answer:
y=-x-8
Step-by-step explanation:
