Answer:

x=1

y=2

Step-by-step explanation:

Multiply the second equation by 2

and then solve!

Answer:

1 and 2

Step-by-step explanation:

4x+4y=12...eqn1^st

2x+y=4....eqn2^nd×2

multiplying eqn2^nd by 2 and subtract then,

4x+4y=12

-4x-2y=-8

or, 2y=4

or, y=4/2

y=2

again ,

from eqn2^nd

we have,

2x+y=4

or, 2x+2=4

or, 2x=4-2

or, 2x=2

or,x=2/2

x=1
