	Video Transcript: Algebra Nspirations: Solving Systems of Equations	Video Transcript: Algebra Nspirations: Solving Systems of Equations This is the transcript for the video of same title. Video contents: Written and hosted by internationally acclaimed math educator Dr. Monica Neagoy, this video introduces students to systems of linear equations in two or three unknowns. To solve these systems, the host illustrates a variety of methods: four involve the TI-Nspire (spreadsheet, graphs and geometry, matrices and nSolve) and two are the classic algebraic methods known as substitution and elimination, also called the linear combinations method. The video ends with a summary of the three possible types of solutions. Concepts explored: equations, linear equations, linear systems	Applications of Linear Systems, Matrix Operations and Solving Systems of Equations
