Hi.
Is it possible to solve five or more simultaneous equation in CASIO fx-991ES calculator? I am in dire need to know on this. Cause this will help me a lot in forthcoming exam. Respond from any one will be highly appreciated. Here i a giving an example

v-w+x=0
w-y+z=0
5v-3x=15
4w+3x+2y=15
y+4z=15

I want to get the value of v,w,x,y and z.

Regards and thanks.

See the manual, p. E-29, last sentence.

You will have to do it with your brain. Using the ancient art of algebra, as documented about 1200 years ago by Mr. Al Kwharizmi (probably) from Khiva, Xorazm, currently in Uzbekistan, his name is nowadays still used - "algorithm".

He already went further than your simple linear equations, he also was capable of solving quadratic equations.

Good luck with the exam !
