Extending elimination to three unknowns, the order in which variables are removed, and back-substitution.
Two equations in two unknowns, the two elementary methods, and the geometric meaning of a solution as an intersection.
Solve systems graphically by interpreting intersections, coincident lines, parallel lines and overlapping inequality regions.
