(Solved) Systems of equations can be solved by graphing or by using substitution or elimination...More?

Firstly Pros and Cons

Graphing:
Good for visualization on what you are looking for an answer but sometime you can't get the answer. Like if the answer turns out to be a decimal number because graphs are usually set up with whole numbers.

Substitution:
You can get your answer correct rather its a whole or a decimal answer but the process can be very long and messy which could cause you to put the wrong information in a spot that it shouldn't be in. Which would cause you then to end up with the wrong answer.

Elimination:
Still get your answer correct rather its a whole or a decimal answer and is not as messy as substitution. More of a chance to having the answer correct the first time around.

The system that I like best would have to be Substitution because it is more of a challenge (specially when you are trying to solve a problem with three or more systems of equations). It tests me on rather I could be neat and not lose my position on where I need to put something. The circumstances that would cause me to use a different method would be on an exam. Exams are usually timed and you would have to be done within that time. Whats not completed is counted as wrong and you don't want to do the long way to take up your time and a chance of making a mistake and getting it incorrect. The only time I would you use it on an exam though is if the directions told me specifically to use substitution (or even graphing).
