Just the answer without the options does not make any sense... Please edit the original post and provide the answer choices. Thank you.

Of course, sorry.

I still dont get it. I solved the question as follows:

m - 1+2m^2/ 2m= y/m (*2m)
2m^2 - (1+2m^2) =ym
4m^2-1 = ym <-- and here I realised Im stuck.

Can you please tell me where I messed it up?!

If m≠0 and \(m-\frac{1+2m^2}{2m} = \frac{y}{m}\), then y is...?

(A) -1
(B) -1/2
(C)-(1+4m^2)
(D) -1+4m^2/2
(E) (2m+1)^2

Multiply both sides by 2m:

\(2m^2-(1+2m^2)= 2y\) --> \(-1=2y\) --> \(y=-\frac{1}{2}\).

Answer: B.

Hope it's clear.
