    word problem secret

    Five times a number is the same as the number added to five. What is the number?

    OK, so 5X=X+5
    X=(X+5)/5

    I know the answer is 5/4, but that took a lot of time- consuming trial and error on my part; is there a way to see through this more quickly?

    If 5X=X+5 then 4X=5 so X=\frac{5}{4}.
