Answer:

x=3

Step-by-step explanation:

4(x-3)=?

distribute: 4x-12=?

Add 12 on both sides to leave 4x on one side: 4x-12+12=12

4x=12

now isolate the variable by dividing 4 on each side: 4x/4=12/4

x=3

Option A. is correct for the given condition.

Lets solve it through steps of range and functions,

First of all, Solve the equation:
$f(x) = |x|+5$
$= > x = -5$ (1)

$= > x = 5$ (2)

So these would be the ranges of X in between 5 and -5.

Hence option A. $R{f(x)eR [f(x) < 5}$ is correct.
