Question

Let g(x)=2x+5. Find x if g(x)=11. 

The value of x is __ if g(x)=11. (Type an integer or a fraction.) 

Answer 1

Hello, thank you for taking the time to post your question!

To solve this one you want to set g(x) = 11 then solve for the value of “x” that makes it true

2x + 5 = 11

2x = 6

x = 3

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

11 = 2x + 5

Subtract 5 from both sides:

6 = 2x

Divide by 2:

3 = x
