How to use scientific calculator to calculate simultaneous equation

Follow these steps to use a scientific calculator to solve simultaneous equations:

1. Enter the coefficients of the variables and constants in each equation into the calculator. For example, if you have the equations 2x + 3y = 10 and 3x - 2y = 4, you would enter the following values:
- For the first equation: 2, 3, and 10
- For the second equation: 3, -2, and 4

2. Use the calculator's function for solving systems of equations. This may be labeled as "Solve" or "Simultaneous Equations" depending on the specific model of calculator you are using.

3. Press the "Enter" or "Equals" button to calculate the solution. The calculator will display the values of x and y that satisfy both equations simultaneously. In this case, the solution would be x = 2 and y = 2.

4. Check your solution by substituting the values of x and y back into both original equations to ensure they satisfy both equations.
