Final Answer : 2 + 2√2
By using eq. of log.
By squaring and solving second equation we get,
(y-2)x = 1
Then, substitute value of
Now,
substitute value of y= 1/(x-2) ,
we get quadratic
x^2-2x-1=0
Solve this
these equations
x = 1-√2 and y = 1-√2
And x = 1 + √2 and y = 1 + √2
We reject first solution since,
x > 2
So, finally
x + y = 2 + 2√2

Please, elaborate your answer when your are free.
*you are
sure,
Can u tell , which part you don't understand
We both got same answer that is y = 1/x - 2 and x = 1/y-2. After this What u did, did u substituted the values of x and y in equation (2)?
yes then, solve quadratic
Thanks for helping.

howdy!!
your answer is in this pic.
value of x is 1+√2
so , x +y = x + x = 1+√2+1+√2 = 2+2√2
option (C) is right
hope it help you
