just substitute the equation with the given number

4x-2y-z
4(2) - 2(3) - (-10)
8-6+10
12

Answer is $= 12$ $=12$

Given -

$4 x - 2 y - z$ $4x-2y-z$

Substitute $x = 2; y = 3 and z = - 10$ $x=2; y=3 and z=-10$ in the above expression.

$= 4 (2) - 2 (3) - (- 10)$ $=4(2)-2(3)-(-10)$
$= 8 - 6 + 10 = 12$ $=8-6+10=12$
