![]() ![]() A 3x3 System of Equations is a system of three equations with three variables that are solved. The typical orientation for the three axes are shown below. solve a 2x2 system of equations by elimination (review). The 3-D coordinate system has three perpendicular axes and uses ordered triples ( x, y, z) to represent a point in space. Let's take a quick look at how graphing is accomplished in 3-D: And like the "strange" situations we encountered in 2-D, there will also be the possibility of "strange" situations occurring in 3-D space. Most graphing calculators do not graph in 3-D. Students will solve 3×3 systems of equations using technology.Methods such as inverse matrices, augmented matrices, or utilization of online calculators are. This poses a problem in that graphing in 3-D can be difficult to visualize since we are looking for the intersection of three planes (not three lines).

When working with a 3x3 system where the three variables are each of degree one (such as x, y, and z), we are dealing with the 3-dimensional Cartesian space. There is also the possibility that we may be dealing with "strange" situations such as the lines being parallel (no solution), or the lines coinciding (lying on top of one another with an infinite number of solutions). Such graphing may be done by hand or on a graphing calculator. ![]() We can solve such a system by graphing the lines on a set of axes in the 2-dimensional Cartesian plane and finding the point of intersection. When working with a 2x2 system, for example, where the two variables are each of degree one (such as x and y), we are dealing with two straight lines. ![]()
