Question

The solution of the pair of equations x – y = 0, 2x – y = 2 is: (a) x =1, y = 1 (b) x =2, y = 2 (c) x =3, y = 3 (d) x =4, y = 4​

Answer 1

Step-by-step explanation:

let x=y

2x-y=2

2y-y=2

y=2

therefore

x=2

option b is correct

Answer 2

Answer:

Step-by-step explanation:

Ans:b

if x=2,y=2

x-y=2-2=0,

2x-y=(2*2)-2=4-2

=2
