If I have $22x = 23y = 24z$ and $x+y+z = 3865$ how to obtain the values of $x$,$y$ and $z$ ?

use $ y = \frac{22}{23}x$ and $z = \frac{22}{24}x$ in last equation.

First, try to express $y$ and $z$ by $x:$

$22x = 23y\Leftrightarrow y = \frac{22}{23}x$

$22x = 24z\Leftrightarrow z = \frac{11}{12}x$

Then put this into your term to find the value of $x\colon$

$x+y+z=3865\Leftrightarrow x+\frac{22}{23}x+\frac{11}{12}x=3865$

Now you have the value of $x.$ To figure out $y$ and $z$ is left as an exercise to you.
