Solve for x x-1/(x-5)=5/(x-5)

$x - \frac{1}{x - 5} = \frac{5}{x - 5}$

Find the LCD of the terms in the equation.

Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.

$1, x - 5, x - 5$

The LCM is the smallest positive number that all of the numbers divide into evenly.

1. List the prime factors of each number.

2. Multiply each factor the greatest number of times it occurs in either number.

The number $1$ is not a prime number because it only has one positive factor, which is itself.

Not prime

The LCM of $1, 1, 1$ is the result of multiplying all prime factors the greatest number of times they occur in either number.

$1$

The factor for $x - 5$ is $x - 5$ itself.

$(x - 5) = x - 5$

$(x - 5)$ occurs $1$ time.

The LCM of $x - 5, x - 5$ is the result of multiplying all factors the greatest number of times they occur in either term.

$x - 5$

Multiply each term in $x - \frac{1}{x - 5} = \frac{5}{x - 5}$ by $x - 5$ to eliminate the fractions.

Multiply each term in $x - \frac{1}{x - 5} = \frac{5}{x - 5}$ by $x - 5$ .

$x (x - 5) - \frac{1}{x - 5} (x - 5) = \frac{5}{x - 5} (x - 5)$

Simplify the left side.

Simplify each term.

Apply the distributive property.

$x \cdot x + x \cdot - 5 - \frac{1}{x - 5} (x - 5) = \frac{5}{x - 5} (x - 5)$

Multiply $x$ by $x$ .

$x^{2} + x \cdot - 5 - \frac{1}{x - 5} (x - 5) = \frac{5}{x - 5} (x - 5)$

Move $- 5$ to the left of $x$ .

$x^{2} - 5 \cdot x - \frac{1}{x - 5} (x - 5) = \frac{5}{x - 5} (x - 5)$

Cancel the common factor of $x - 5$ .

Move the leading negative in $- \frac{1}{x - 5}$ into the numerator.

$x^{2} - 5 x + \frac{- 1}{x - 5} (x - 5) = \frac{5}{x - 5} (x - 5)$

Cancel the common factor.

$x^{2} - 5 x + \frac{- 1}{x - 5} (x - 5) = \frac{5}{x - 5} (x - 5)$

Rewrite the expression.

$x^{2} - 5 x - 1 = \frac{5}{x - 5} (x - 5)$

Simplify the right side.

Cancel the common factor of $x - 5$ .

Cancel the common factor.

$x^{2} - 5 x - 1 = \frac{5}{x - 5} (x - 5)$

Rewrite the expression.

$x^{2} - 5 x - 1 = 5$

Solve the equation.

Subtract $5$ from both sides of the equation.

$x^{2} - 5 x - 1 - 5 = 0$

Subtract $5$ from $- 1$ .

$x^{2} - 5 x - 6 = 0$

Factor $x^{2} - 5 x - 6$ using the AC method.

Consider the form $x^{2} + b x + c$ . Find a pair of integers whose product is $c$ and whose sum is $b$ . In this case, whose product is $- 6$ and whose sum is $- 5$ .

$- 6, 1$

Write the factored form using these integers.

$(x - 6) (x + 1) = 0$

If any individual factor on the left side of the equation is equal to $0$ , the entire expression will be equal to $0$ .

$x - 6 = 0$

$x + 1 = 0$

Set $x - 6$ equal to $0$ and solve for $x$ .

Set $x - 6$ equal to $0$ .

$x - 6 = 0$

Add $6$ to both sides of the equation.

$x = 6$

Set $x + 1$ equal to $0$ and solve for $x$ .

Set $x + 1$ equal to $0$ .

$x + 1 = 0$

Subtract $1$ from both sides of the equation.

$x = - 1$

The final solution is all the values that make $(x - 6) (x + 1) = 0$ true.

$x = 6, - 1$

Solve for x x-1/(x-5)=5/(x-5)
