Respuesta :

A)6 b)4 c)2 d)0. You just have to replace X with given number.

Answer:

Soln:

Firstly, putting -2 as the value of x

y=4-x

or, y=4-(-2)

or, y=4+2

or,y=6

:. y=6

Now, putting 0 as the value of x

y=4-x

or, y=4-0

or, y=4

:. y=4

Again, putting 2 as the value of x

y=4-x

or, y=4-2

or, y=2

:. y=2

Lastly, putting 4 as the value of x

y=4-x

or, y=4-4

or, y=0

:. y=0

Therefore,(a)x=-2 , y=6

(b)x=0 , y=4

(c)x=2 , y=2

(d)x=4. , y=0
