Question

If f(x)=9x+2, for what value of x is the value of the function 29?

Answer 1

Answer shown below.

Explanation:

For 29;

It means f(x)= 9x + 2 =29

Therefore; 9x =29-2=27

9x = 27

X=27/9

x=3

Answer 2

The answer is 3.

Explanation:

In oder to find the value of x you have to let f(x) = 29 :

`f(x) = 9x + 2`

Let f(x) = 29

`9x + 2 = 29`

Next, you have to solve x by substracting 2 and divide 9 to both sides :

`9x + 2 = 29`

`9x + 2 - 2 = 29 - 2`

`9x = 27`

`9x / 9 = 27 / 9`

`x = 3`
