SV#5 - Unit J Concepts 3-4: Matrices

Don't be scared when you look at this problem! It's actually really easy even though it's a lot of work! (HENCE MY 8 MINUTE VIDEO, SORRY ABOUT THAT) Be sure to simplify equations when you can so you can make your life so much easier when add/subtracting! Remember, our goal is to get our matrix to be in the Row- Echelon form. This means there will a right triangle of 0's and a staircase of 1's! Follow the Gaussian Elimination and you'll be in good hands. Remember that if you have a consistent dependent, solve until the very end in the matrix even if it means you'll have 2 rows left. Be sure to plug in the value of each letter correctly to ensure an accurate answer at the end.
