Answer:

x = 0 and y = 4.

Step-by-step explanation:

The given equations are :

4x+2y=8 ...(1)

x+y=4 ...(2)

Multiply equation (2) by 2.

2x+2y=8 ...(3)

Subtract equation (3) from (1).

4x+2y-(2x+2y)=8-8

4x+2y-2x-2y=0

2x = 0

x = 0

Put the value of x in equation (2).

0+y=4

y = 4

So, the value of x and y are 0 and 4.
