we can isolate y in every equation

a) y = -4x+5

b) y = 4x-5

c) y= 4x-5

d) y=4x+5

Now apply this y value for 4x-y = 5

in (b) , (c) , (d)  

we got answer as 5 = 5

but in (a)

4x-y =5

apply y value

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

4x +4x-5 = 5

8x = 10

x= 10/8

x= 5/4

we can apply this x value for y= -4x+5

y= -4(5/4)+5

y=-5+5

y=0

so there is solution answer is (a)

y = -4x+5
