In this video, I show you how to efficiently solve systems of equations on the graphing calculator, specifically the TI84 Plus Ce and TI84 Plus Silver Edition. This should be relevant to any other similar models as well.

The steps are:
1. Hit the "Apps" button on your calculator.
2. Select "PlySmlt2"
3. Select "SIMULTANEOUS EQN SOLVER"
4. Select the number of equations and number of unknowns (for the example in the video it is 2 for both cases)
5. Hit the "graph" button to select next
6. Enter the coefficients for x,y, and the constants in that respective order (make sure to use the negative sign NOT the minus sign)
7. Hit the "graph" button to solve the system of equations

Hope this helps!
