If and then

We have,

…(i)

Also, …(ii)

Now, multiplying (ii) by 2 and then subtracting it from (ii) we get:

∴ y = 1

Now substituting the value of y in (ii), we get:

Hence, option B is correct

If 29x + 37y = 103 and 37x + 29y = 95 then

If 2^{x + y} = 2^{x – y} = √8 then the value of y is

The system kx – y = 2 and 6x – 2y = 3 has a unique solution only when

The system x – 2y = 3 and 3x + ky = 1 has a unique solution only when
