Question

x=2, y= -1 is a solution of the linear equation:-
x+2y=0
x+2y=4
2x+y=0
2x+y=5​

Answer 1

Answer:

1.x=2, y= -1 is a solution of the linear equation:-

•x+2y=0 is a correct option.

Step-by-step explanation:

•x+2y=0

put x=2, y= -1

2+2×(-1)=0

2-2=0

0=0

L.H.S=R.H.S

•x+2y=4

put x=2, y= -1

2+2×(-1)=4

2-2=4

0=4

L.H.S is not equal R.H.S.

•2x+y=0

put x=2, y= -1

2×2+(-1)=4

4-1=4

3=4

L.H.S is not equal R.H.S.

•2x+y=5

put x=2, y= -1

2×2+(-1)=5

4-1=5

3=5

L.H.S is not equal R.H.S.
