Solving Systems of Linear Equations in Three Variables
A system of equations in three variables is any system that essentially contains three unknown quantities. The variables x, y, and z are usually used to represent these unknown values. Needless to say, a system of linear equations in three variables is a system that meets both conditions listed above. While a system of equations can contain any ...
