Given the function f(x) = 2(x + 10), find x if f(x) = 24.

Solution:

Given, function f(x) = 2(x + 10)

We have to find the value of x when f(x) = 24

By multiplicative and distributive property,

2(x + 10) = 2x + 20

So, f(x) = 2x + 20

Using the distributive property

2x + 20 = 24

By further calculation

2x = 24 - 20

2x = 4

Dividing both sides by 2

x = 4/2

x = 2

Therefore, the value of x is 2.

Given the function f(x) = 2(x + 10), find x if f(x) = 24.

Summary:

Given the function f(x) = 2(x+10), if f(x) = 24 the value of x is 2.
