Question

Let f(x) = 2x+4. If f(x) = 16, find x.

Answer 1

$f(x)=2x+4$

And we are given that $f(x)=16$ and want to find the value of x. Set f(x) to 16 and we get the equation:

$2x+4=16$

Subtract both sides by 4

$2x=12$

Divide both sides by 2

$x=6$

This is the answer. Let me know if you need any clarifications, thanks!

Answer 2

Given-
f(x)=2x+4
f(x)=16
So,
=> 2x+4=16
Subtract 4 both both the sides
=>2x=12
=>x=12/2
=>x=6
So the Answer is x=6
Hope it helps you!
