Always let x and y answer the question -- and be perfectly clear about what they represent! Since there are two unknowns, there must be two equations. (In general, to have a unique solution, the number of equations must equal the number of unknowns.) ,A solution of a system of equations is an ordered pair of numbers that satisfies both equations. A system of two linear equations can have 0, 1, or an infinite number of solutions. • If the graphs intersect or coincide, the system of equations is said to be. That is, it has at least one ordered pair that satisfies both equations.
