1. Turn on the calculator: Press the ‘ON’ button located at the bottom left corner of the calculator.
2. Select the correct mode: Press the ‘MODE’ button near the top of the calculator. Ensure that you are in the correct mode for your calculations (e.g., standard, scientific, or graphing).
3. Open the Y= editor: Press the ‘Y=’ button located at the top of the calculator’s keypad.
4. Locate the stored X value: Scroll through the functions until you find the one that contains the stored X value you wish to clear.
5. Highlight the stored X value: Use the arrow keys to navigate to the stored X value.
6. Delete the stored X value: Press the ‘CLEAR’ or ‘DEL’ button to remove the stored X value.
7. Clear other variables: If there are any other variables or data that need to be cleared, repeat steps 5 and 6.
8. Exit the Y= editor: Once you have cleared all the necessary variables, press the ‘2ND’ button followed by the ‘MODE’ button to exit the Y= editor.

You have successfully cleared the stored X value on your TI-84 calculator. Now you can perform calculations without any interference from previous data.
