Unformatted text preview: equations are dependent. Cons : Graphing alone is not perfectly accurate, and may give only approximate answers, and not always the fastest method. Exact fraction solutions are difficult to determine graphically. Substitution Pros : Method is faster and more accurate than graphing. Cons : To be careful when removing parentheses as you can easily make a mistake. Solutions not quickly seen with fractions and computations can be extensive. Elimination Pros : Method is faster and more accurate than graphing, and easier than substitution for some systems. Cons : Can not see solutions quickly. I like both the Substitution and Elimination Methods, but would choose the Elimination Method as first choice. I like these two methods because they are faster and you can get a more accurate answer. The only circumstance I can think of using graphing is if asked to because I needed to show my work....
