$2 x - 3$

Explanation:

$f \left(x\right) = 4 x - 3 - \left(x + 1\right) + \left(1 - x\right)$

Remove the brackets
$f \left(x\right) = 4 x - 3 - x - 1 + 1 - x$

Bring together terms in $x$ and constants
$f \left(x\right) = 4 x - x - x - 3 - 1 + 1$

Sum terms in $x$ and constants
$f \left(x\right) = 2 x - 3$
