Question about Casio FX9750GII Graphic Calculator
Here how it is done. Don't mind the calculator it was done on. On your you may have systems of up to 3 linear equations.
Follow the screen captures. I do not think any additional comments are warranted. Pressing the F1 key (REPT)-- see last screen capture--allows the user to repeat the solution with the same coefficients or other ones (different system)

SOURCE: Factoring polynomials "Algebra"
choose equation format "4"
input the coefficient for a which is "1" and hit "="
input the coefficient for b which is "4" and hit "="
input the coefficient for c which is "3" and hit "="
input the coefficient for d which is "12" and hit "="
Hit "=" for X1
Hit "=" again for X2
Hit "=" again for X3

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

Turn calculator ON. If you do not see several icons press [MENu].
Use arrow to select the [GRAPH] application and press [EXE].
In the entry screen, the line with Y1= is highlighted. If it is not, use arrow to highlight it.
Press the right arrow, the highlighting disappears leaving you with Y1= and the blinking cursor.
At the position of the cursor enter 5 [X, theta,T] key under the [ALPHA]. On the screen appears 5X, complete you equation +2.
Press [EXE] to store function.
If you want to draw other functions, it is time to do so on that screen.
When done press [F6:Draw}.
If the screen does not show a lot of the function, you can use the arrow keys to pan the graph.
You can also press [SHIFT][V-Window] to set the window limits.
Hope it helps.

Testimonial: "Thank you so much!!!"
There is a function to calculate them for you.
In CAS, or Algebra or Tutor Modes, use the x! option
In Run-Math, press [OPTN][F6] to pan right, then [F1] to access the (PROB) menu then enter option number corresponding to x!
The way it works is as follows
number ! [EXE].
Due to memory limitations, you can calculate factorials of numbers up to 69.
Hope it helps.
