12 is correct, but imo, I think you should be more confident With Your own work. If you solve a problem but are doubtful about about your result, you should concentrate on the systems that exist to check your answers.
This is pretty basic but the same concept applies.
You're asked to solve
4x +3 = 7
You solve algebraically and get x=1.
You're not 100% gone it is correct, but you Know how to check it by Inserting x=1 back into the original equation.
You do so and you end UP with
7=7
Thus you have proven to yourself that x=1 is indeed the correct solution"
Methods of "checking" your answers are actually systems of "proof" The more involved you become with checking your own answers, the more confident you Will be with your own work to the point where you won't have to ask anyone to check your work for you.
