X + y + z = 6
X + 2y = 5
2x + z = 5
X + y + z = 6
X + 2y = 5
2x + z = 5
- First you have to pick 2 equations and try to eliminate x
- multiply one of the equations by a nonzero constant before adding in order to eliminate one of the variables.
- Eliminate the variable by either multiplying or subtracting
- Continue this method with 2 different equations and try to continue to eliminate different variables
