Conclusion
The substitution method of solving systems of linearequations may work well if there are only 2 variables.If there are 3 or more variables, it can become a nightmare.

Conclusion
The addition method of solving systems of linearequations sometimes works well if there are only 2 or 3equations.However, it’s easy to get lost if you don’t keep organized.Far worse, if you just work haphazardly, you can get wronganswers!
