For this case we have a function of the form
y = g (x)

Where:

g (x) = 2 (x-4)

We must find the value of "x" when the function has a value of 20, that is,
g (x) = 20 :

2 (x-4) = 20

We apply distributive property:

2x-8 = 20

We add 8 to both sides of the equation:

$2x = 20 + 8\\2x = 28$

We divide between 2 on both sides of the equation:

$x = \frac {28} {2}\\x = 14$
