Question

2x+y=6; x+2y=6; 7x-4y =6

Answer 1

here x=y=2

2x+y=x+2y

2x-×=2y-y

x=y

Answer 2

Step-by-step explanation:

2x+y=6

2x=6-y

x=6-y/2

x=3-y/2

x+2y=6

substitute the given x value in this equation..

3-y/2 + 2 (y ) =6

6-y+4y/2=6

6+3y/2=6

6+3y=12

3y=12-6

3y=6

y=2

substitute this y value in x equation

3-y/2=x

3-2/2=X

3-1=X

2=X

Therefore,

X=2

Y=2
