Solving Systems of Linear Equations in Three Variables
One way to solve a system of linear equations algebraically is to use the . elimination. method. Consider the system of equations . x – y = 3 and 2. x + y = 6. The second equation above states that 2. x + y. is equal to 6. So, if you take the first equation (x – y = 3) and add 2. x + y.

To solve such a system means to find the coordinate triple (x, y, z) that makes all three equations a true statement. A Graphical Representation. Whereas linear equations in two variables are graphed as lines in the two-dimensional Cartesian coordinate plane, linear equations in three variables require three-dimensional space to be graphed.
