This chapter discusses linear equation in two variables. Elementary algebra deals with equations such as 3 x = 5, x 2 y = 8, and x + 3 y 2 z = 14. These are classed as first-degree equations, also called linear
Determine whether the ordered pair (–2,4)(–2,4) is a solution of the system of equations: −x+2=y2x+y=8−x+2=y2x+y=8 Show Answer Classifying a System of Linear Equations in 2 Variables In addition to considering the number of equations and variables, we can categorize a sy...

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation...
Two linear equations in two unknowns are solved graphically, and analytically by several techniques, including Cramer's rule. Note: In Maple 2018, context-sensitive menus were incorporated into the new Maple Context Panel, located on the right side of the Maple window. If you are using Maple ...
