Will give brainliest is steps are listed out.

Musya8 [376]

Answer:

Step-by-step explanation:

Write the expression out

factor it

$(\frac{(x+1)(x-1)}{6x})(\frac{3x(x)}{x(x+1)})$

cancel out all everything that is the same and appears on both the top and the bottom

Cancel out:

(x+1)

(x)

leaves you with

$\frac{3(x-1)}{6}$

3 goes into 6 '2' times so the 3 in the numerator cancels out too. The 6 in the denominator turns into a 2

This leaves you with the final answer of

$\frac{x-1}{2}$
