Systems of Linear Equations in Three Variables
In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables (x,y,z), ( x , y , z ) , is called an ordered triple.
ordered triples
The form (x, y, z) represent the location of a point in coordinate space.
Systems of linear equations
is a set of two or more linear equations in the same variables.
inconsistent
not staying the same throughout
Linear
straight line
