Question 136875
Systems of equations can be solved by graphing or by using substitution or elimination. What are the pros and cons of each method? Which method do you like best? Why? What circumstances would cause you to use a different method?

------------------
Graphing is find if you want a quick guestimate of the solution.
Substitution is good if one of the equation can easily be solved 
for one of the variables.
Elimination is always good as a last resort if graphing is not 
accurate enough or if both of the equations are complicated.
