My Crazy math teacher says this is solvable

  1. Jan 21, 2005 #1
    [tex]
    \\x-\frac {x}{1}=\frac{12}{25} ...then...\\x-x=\frac{12}{25}\\ ...then...0=\frac{12}{25}

    [/tex]


    .... I hope not....

    Is there a way? It was on homework and he says that all of them have answers. He didnt direct any comment on this problem. btw, only the first part is actaully on the problem, the part after the first "then" is what I got.

    Your problem has no solution in any field where 1 is the multiplicative identity, much less in the real numbers. The problem may have been a typo of x - 1/x = 12/25.

    did the problem ask you to solve for x? x is not solvable.....100%.... period
    that might be a typo or something alike....
    you might wanna make sure the question is not "is x solvable" j/k

    A number "n" cannot be subtracted by an identical value and result in a positive value.

    The answer could be something like "unsolvable."

    Yeah, I emailed my teacher and he said it was a typo ;)
