Linear systems and matrices are used to model and solve real-world problems. In this unit, students formalize their understanding of linear systems and matrices. In Algebra 1, students solved linear systems of two equations. Students begin this unit by solving applications involving systems of two equations. Students solve linear systems of three equations in three unknowns. Operations on matrices, such as addition, subtraction, scalar multiplication, and matrix multiplication, are studied. Students evaluate the determinant of a matrix and find the inverse of a square matrix. Systems of equations are solved using matrix equations and inverse matrices. In an optional enrichment section, systems of equations are solved using augmented matrices.
