Answer

There is no solution.

Solution

Start with the equation:   x/(x - 5) - 3 = 5/(x - 5) Step 1. Since the denominator is x - 5, note that x cannot equal 5. Step 2. Multiply every term by (x - 5) (which is allowed, since x ≠ 5):   (x/(x - 5))·(x - 5) - 3·(x - 5) = (5/(x - 5))·(x - 5) This simplifies to:   x - 3(x - 5) = 5 Step 3. Expand and simplify:   x - 3x + 15 = 5   -2x + 15 = 5 Step 4. Solve for x:   -2x = 5 - 15   -2x = -10   x = (-10)/(-2)   x = 5 However, x = 5 is not allowed because it makes the denominator zero. Thus, there is No solution.

The Deep Dive

To solve the equation \[ \frac{x}{x-5}-3=\frac{5}{x-5}, \] first, we can combine the fractions on the left side. We rewrite \(-3\) as \(-\frac{3(x-5)}{x-5}\) to have a common denominator: \[ \frac{x - 3(x-5)}{x-5} = \frac{5}{x-5}. \] Next, simplify the numerator: \[ \frac{x - 3x + 15}{x-5} = \frac{5}{x-5}. \] This simplifies to: \[ \frac{-2x + 15}{x-5} = \frac{5}{x-5}. \] Since the denominators are the same, we set the numerators equal to each other: \[ -2x + 15 = 5. \] Now, solve for \(x\): \[ -2x = 5 - 15, \] \[ -2x = -10, \] \[ x = 5. \] However, this value causes the original expression \((x-5)\) to be zero, resulting in an undefined expression in the fractions. Therefore, there are no valid solutions. No solution.
