Question

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

Answer 1

Answer:

The answer is 3.

Step-by-step 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 :

$9x + 2 = 29$

$9x + 2 - 2 = 29 - 2$

$9x = 27$

$9x \div 9 = 27 \div 9$

$x = 3$

Answer 2

Answer:

Answer shown below.

Step-by-step explanation:

For 29;

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

Therefore; 9x =29-2=27

9x = 27

X=27/9

x=3
