12=x+3 please help me out

Hello there! :)

Answer:

[tex]\boxed{x=9}[/tex]

*The answer must have a POSITIVE sign!*

Step-by-step explanation:

First, you switch sides of an equation.

[tex]X+3=12[/tex]

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

[tex]X+3-3=12-3[/tex]

You subtract by the numbers from left to right.

[tex]12-3=9[/tex]

Final answer is →→ [tex]\boxed{X=9}[/tex]

Hope this helps!

Thank you!

Have a nice day! :)

:D
