Subtract 1 from 2

we get Y = -1 + 2z

and from 2 we know X = 2 - 2Z

Hence putting the value of X and Y in X/2 + Y = Z

We, get Z = 1

hence, C is the correct answer.

Feedback will be appreciated.

Thank you.

Hence putting the value of X and Y in X/2 + Y = Z

=> (2-2z)/2+(-1+2z)= z

=> (1-z)+(-1+2z)=z

=> 1-z-1+2z=z

=>z=z

At end we just got z=z. Can you please check how you got z=1 ???? . We are not getting value of z at the end .

Answer should be E
