Hello there! :)

Answer:

$\boxed{x=9}$

*The answer must have a POSITIVE sign!*

Explanation:

First, you switch sides of an equation.

X+3=12

Then, you subtract by 3 from both sides of an equation.

X+3-3=12-3

You subtract by the numbers from left to right.

12-3=9

Final answer is →→
$\boxed{X=9}$

Hope this helps!

Thank you!

Have a nice day! :)

:D
