"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 the best? Why? What circumstances would cause you to use a different method? Consider responding to your classmates by indicating pros and cons they may not have considered or persuading them to see the value of the method you like best . Describe situations in which you might use their methods of solving."

My crystal ball is in the shop for repairs.

How do we -- total strangers -- know which method you like best???

Why did you post this question here? We're a homework help site, not a mind-reading site.

What are the pros and cons of each method?

These are your keys.

Graphing gives a visual representation of the system of equations as well as an approximate solution. Substitution and elimination both give accurate mathematical results (ignoring rounding errors). Which technique to use is often problem dependent.

This should give you a headstart. Complete your text and we will be glad to review it for you.
