Hi there!

I believe your answer is:

`x = 1`

Here’s why:

⸻⸻⸻⸻

`\boxed{\text{Calculating the answer...}}\\\\3x + 9 = 12\\-------------\\\rightarrow 3x + 9 - 9 = 12 - 9\\\\\rightarrow 3x = 3\\\\\rightarrow (3x=3)/(3)\\\\\rightarrow \boxed{x=1}`

Hope this helps you. I apologize if it’s incorrect.

Answer 2

x=1

Explanation:

3x+9 = 12

Subtract 9 from each side

3x+9-9=12-9

3x = 3

Divide by 3

3x/3 = 3/3

x=1
