Using Matrices to Solve a System of Two Equations: SMART Board Resource for Algebra 2 (Grades 6-12) (eLesson Plan)
One of the last examples on Systems of Linear Equations was this one:Example: Solve x + y + z = 6 2y + 5z = −4 2x + 5y − z = 27We went on to solve it using "elimination", but we can also solve it using Matrices!
