Answer 1

but what we have to find in question

Answer 2

Answer:

for elimination method,first multiply the first equation by 2 to make coefficient of x equal.

Step-by-step explanation:

Now, 4x+4y =20 and 4x+y = 20

subtract second equation from first.

then, 4x-4x + 4y-y = 20-20

or, 3y= 0 or, y=0

putting value of y in second equation,we get 4x+0 = 20

or x= 20/4 =5
