Answer:
The value of x is [tex]14[/tex]
Step-by-step explanation:
we have
[tex]g(x)=2(x-4)[/tex] ------> equation A
In this problem we have
[tex]g(x)=20[/tex]
Substitute the value of g(x) in the equation A and solve for x
[tex]20=2(x-4)[/tex]
Divide by [tex]2[/tex] both sides
[tex]20/2=2(x-4)/2[/tex]
[tex]10=(x-4)[/tex]
Adds [tex]4[/tex] both sides
[tex]10+4=(x-4)+4[/tex]
[tex]x=14[/tex]
