    You got the x=5 part right, but to tell whether or not a solution is extraneous or not, you plug it back in and see what you get. What happens when you plug in x=5?

    Well, specifically, look at the denominators. Work with the left side first. \(\frac{5}{x-5}\). When you plug in x=5 here, what is in the denominator?

    5/5-5=5/0=undefi.

    Yup. Since you got 0 in the denominator, when x=5, the equation is undefined. Therefore, the solution doesn't work, and it is extraneous.
