Given the function f(x) = 2(x + 4), find x if f(x) = 22.

Solution:

Given, function f(x) = 2(x + 4)

We have to find x when f(x) = 22.

By multiplicative and distributive property,

2(x + 4) = 2x + 8

2x + 8 = 22

By further calculation

2x = 22 - 8

2x = 14

Dividing both sides by 2

x = 14/2

x = 7

Therefore, the value of x is 7.

Given the function f(x) = 2(x + 4), find x if f(x) = 22.

Summary:

Given the function f(x) = 2(x + 4), if f(x) = 22, the value of x is 7.
