Question

The solution of the pair of equations 2x-y=5 and 5x-y=11 is

x=-1,y=2

x=2,y=-1

x=0,y=-5

x=-5,y=0​

Answer 1

Step-by-step explanation:

2x-y=5 ----(i)

5x-y=11 ----(ii)

(ii)-(i)

=3x=6

⇨x=2

putting the value of x to equation (i),

2*2-y=5

⇨-y=1

⇨y=-1

so,(x,y)=(2,-1)

Hope it'll make this clear.
