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

Hello my name is Ivan and in this video we will be solving one of our Doctor Prescription problems. The viewer must pay special attention to the type of solution we have. As seen in the video (and as seen in your work) this problem is an example of a consistent dependent solution, which means there are infinite amount of solutions. However, one must find the restrictions (which come in the form of equations) that make this statement true. To find these, we set an arbitrary value for z and used this so solve for the rest of the variables. Be careful to plug it into your calculator correctly and don't forget to keep your negative values negative. Be sure to identify the type of solution we have an highlight your zero rows to keep your work organized. Thank you and good luck!
