3.4 Systems in Three Variables You are familiar with a 2D coordinate plane. It is has an x-axis and a y-axis.

Z-Axis Today we add a third dimension. The z-axis.

Solving Systems Solving systems in three variables is similar to solving systems with two variables.

Methods Use the substitution or elimination method to solve a system of three variables. Graphing will not be helpful.

Example #1 Solve the system of equations.

Example #2 Solve the system of equations.

Example #3 Solve the system of equations.

Example #4 Solve the system of equations.
