Solve for x 3/4-(2x)/(4x-24)=8/(x-6)

Factor ${\displaystyle 4}$ out of ${\displaystyle 4x-24}$.

Reduce the expression ${\displaystyle \frac{2x}{4(x-6)}}$ by cancelling the common factors.

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

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.

${\displaystyle 4}$ has factors of ${\displaystyle 2}$ and ${\displaystyle 2}$.

Since ${\displaystyle 2}$ has no factors besides ${\displaystyle 1}$ and ${\displaystyle 2}$.

${\displaystyle 2}$ is a prime number

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

Not prime

The LCM of ${\displaystyle 4,2,1}$ is the result of multiplying all prime factors the greatest number of times they occur in either number.

Multiply ${\displaystyle 2}$ by ${\displaystyle 2}$.

The factor for ${\displaystyle x-6}$ is ${\displaystyle x-6}$ itself.

${\displaystyle (x-6)}$ occurs ${\displaystyle 1}$ time.

The LCM of ${\displaystyle x-6,x-6}$ is the result of multiplying all factors the greatest number of times they occur in either term.

The Least Common Multiple ${\displaystyle \mathrm{LCM}}$ of some numbers is the smallest number that the numbers are factors of.

Multiply each term in ${\displaystyle \frac{3}{4}-\frac{x}{2(x-6)}=\frac{8}{x-6}}$ by ${\displaystyle 4(x-6)}$.

Simplify the left side.

Simplify the right side.

Add ${\displaystyle 18}$ to both sides of the equation.

Add ${\displaystyle 32}$ and ${\displaystyle 18}$.
