Today during my adventure in Mathland, I had a flashback to 8th grade and relearned how to solve by substitution. I followed the 4 simple steps.
1. Isolate one variable in one equation.
2. Substitute the variable found in step 1 to the other equation.
3. Solve.
4. Use back substitution to find the remaining variable.
It's as easy as that. I hope my time in Mathland tomorrow will be equally as fun as today.
Wow X, I missed the notes in class and this has served me well. Who needs to listen in class when X takes such detailed and strenuous notes? This is exceptional. Keep up the good work, you are helping me out tremendously!
ReplyDeleteFirst I'd like to thank you for the dollar signs in the background, I appreciate them. Second, thank you for these notes and the explanation! You simplified it down very nicely (:
