ti 83 solving

[newcomp]

how do i solve a function like this on a ti-83 + calc

5+x=15
x=?

i know it is really really easy i just want know how to do it

[biznob]

15 - 5?

you mean you want the calcuator to solve your variables, i dont think that they can do that.

if they could then that would be extremly cheap for tests.....

i know that the 89 can do it, and there was a rumor that the 83+ can do it. i know the 82 cant, and im pretty sure the 83 cant (although the 83+ might be able to....)
usually (at least in my old highschool and here at college) all of the ones that can solve variable equations are banned from tests.

It's F2 under solve.

The equation would look like this: solve(5+x=15,x) I suppose you could also type that in manually if you felt so inclined. BTW, it appears as though you need to take an hour or two to read the manual. This is a simple equation. Your calculator can do much, much more

[EDIT] I have a TI-89, and I know the TI-83+ can do this... but not sure on others.

I think something like this.
Basically, the person has to input X for one of the variables
Disp"A+B=C"
Prompt A
Prompt B
Prompt C
If
A=X
Then
Disp"X is" C-B
If
B=X
Then
Disp"X is" C-A
If C=X
Then
Disp"X is" A+B
DelVar X
DelVar A
DelVar B
DelVar C

on the 83+, do you hit alpha window to get f2? because that doesnt work on my roommates calc. apha window still brings up window...

Does anyone know where or how to get source codes or asm codes for programs

Yes - ticalc has both ti-basic and asm source code for the programs listed. You need a cable to download them and the appropriate software (software free from Texas Instruments). They have many categories. You can view them or use them as examples. Some are excellent, some are good, some don't work because you don't know how the input is formatted (ie how to enter list items - comma between each data item - or ??
