## Precalculus and Advanced Topics Module 2, Topic C, Lesson 14

Student Outcomes

• Students will represent systems of equations as linear transformations of the form Lx = b, using matrix notation.
• Students will discover that the systems of equations written in the form Lx = b can be solved by computing x = L-1b for all invertible matrices, L and they will apply this process to find solutions to systems of two linear equations in two variables.
