The Only Time I Want You To Use Substitution

This video tutorial explains when to use substitution for solving systems of equations. It highlights two scenarios: when both equations are solved for the same variable and when one equation has an isolated variable. The video provides examples for each case, demonstrating the substitution method step-by-step. It concludes with advice on choosing between substitution and elimination, and offers additional resources for further learning.

What is the significance of having a variable isolated in one of the equations when using substitution?

How can practice and experience affect the decision to use substitution or elimination in solving equations?
