The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver.
You cannot use it to solve equations.
Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991.
Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.
SOURCE: Trying to get the inverse of a matrix
Hello,
The error may be due to the key you used to signifie inverse. It says in the manual that you should use the key x^-1 not the one used to input general powers.
Here is screen capture from the Appendix to the manual. The picture shows the sequence of keys to press to obtain the inverse of a 2x2 matrix. It is taken from page 41 of Appendix
The matrix used in the exemple is
a_11=2 a_12=1 a_21=1 a_22=2
Here is the link to download the manual and the appendix

Hope it helps
SOURCE: want to solve quadratic equations on my casio 3650p super fx
Hello,
In your manual, Appendix Program Library, (Page A1) you have the listing of the problem to solve the quadratic equation. Type it in your calculator and execute it.
Hope it helps.
SOURCE: solving multiple non-linear equations
Type it like this: solve( equation1 and equation2 and moreEquations, {list of variables to solve for})
Put all of your equations right after the opening parenthesis separated by the word and, then a comma, then within curly braces each variable you want to solve for each separated by a comma.
SOURCE: Argument error whenever I type equations with variables.
Perhaps you have some data stored in the x variable.
With the calculator on, press [2nd] then the minus button. This brings up a list of all the saved data in the calculator. Look through the far left column of the list for x.
If you find x in the list, highlight x, then press F1, and then select delete.
Now it should work like normal.
SOURCE: TI 89 when solving equations or integrating a message appears:
With the ALPHA keyboard, Type in the NewProb command and press ]ENTER] It resets the one-letter variables to their default status.
Alternatively, you can use the CATALOG of commands to launch the NewProb command.
Another way is
In HOME directory, press the [2nd][F1] to activate the F6 key. In the menu list, press 1:Clear a-z and ]ENTER].
If you have to use the variable x multiplied by a function (sin, cos, tan, log, etc) do not used implied multiplication: enter the [*] explicitly.
