Lesson Plan: Solving a System of Three Equations Using a Matrix Inverse Mathematics
This lesson plan includes the objectives and prerequisites of the lesson teaching students how to solve a system of three linear equations using the inverse of the matrix of coefficients.
Students will be able to
- write a system of equations in matrix form,
- solve a system of three equations using inverse matrices to find a unique solution,
- solve word problems involving a system of three equations using an inverse matrix.
Students should already be familiar with
- finding the inverse of a matrix.
