Note: This chapter deals with sets of linear equations

Recall that a linear equation in two variables is an equation that describes a line and is of the form, ax + by = c. We review solving systems (sets of equations considered together) using 3 methods. ... A determinant of a square matrix is a real number. For a 1x1 it is the only entry. ... Solve using your calculator 3x ( 2y = 0. ................
