Three variable equations

how to solve


1. Pick 2 equations and try to eliminate one variable.

2. Pick another 2 equations and eliminate the same variable.

3. Take the 2 new equations from step 1 and 2 and eliminate another variable.

4. Once you find the value of one variable, back substitute into a 2 variable equation to find the second value.

5 Continue back substitution to find all 3 values.
