Question

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?

Answer 1

The method I like isn't really a formal method

Answer 2

graphing will sometimes only give you an approximate result
elimination is usually easiest for linear equations
if u have mixed equations (like 1 linear and 1 quadratic ) u have to use substitution

i have no preferences

the method i would choose depends on the kind of equations

Answer 3

What circumstances would cause you to use a different method?

Answer 4

If you use elimination method and it doesn't work, try substitution.

Answer 5

If subsititution doesn't work, it's probably no solution or parallel
