Answer:

No

Step-by-step explanation:

if you plug the top equation into the bottom equation, you would get

4x-(5x+2)=0

4x-5x-2=0

-x=2

x=-2

x would equal -2 which would then make y = -8

Answer:

no

Step-by-step explanation:

y = 5x + 2

4x - y = 0

4x - (5x + 2) = 0

-x-2=0

x= -2

replacing in y = 5x + 2

y=5(-2)+2

y=-8

Ans. (-2,-8)
