Final answer:

To solve the equation 5/(x-5) = x/(x-5) - 5/4, we simplify and find that x = 25/9. The solution is not extraneous.

Step-by-step explanation:

To solve the equation, let's first simplify it:

5/(x-5) = x/(x-5) - 5/4

We can multiply both sides of the equation by (x-5) to eliminate the denominator:

5 = x - 5 - (5/4)(x-5)

Now, let's simplify and solve for x:

5 = x - 5 - (5/4)x + 25/4

Combining like terms, we have:

(9/4)x = 25/4

Multiplying both sides by 4/9, we get:

x = 25/9

To determine if the solution is extraneous, we need to check if it satisfies the original equation:

5/(25/9-5) = (25/9)/(25/9-5) - 5/4

Simplifying, we find that both sides of the equation are equal, so the solution x = 25/9 is not extraneous.
