Complete the following table.

S.No.	Expression	Positions on the number line	Conclusions
$\left(\mathrm{i}\right)$	$x+5$		$X$ may be anywhere on the number line, but it is definite that the value of $x+5$ will be $5$ units to the right of $X$.
$\left(\mathrm{ii}\right)$	$3x-5$		The position of $3x$ will be the point $B$. The position of $3x-5$ will be $P$ which is $5$ units to the left of $B$.
$\left(\mathrm{iii}\right)$	$2x+3$	______	______
$\left(\mathrm{iv}\right)$	$3x+2$	______	______
$\left(\mathrm{v}\right)$	$4x-5$	______	______
