Main Question or Discussion Point

Hi everybody,

i was using the " Solve( " function in TI-89 TIT (home) and i inserted the function (* THIS IS EXACTLY WHAT I TYPED IN *) :::::

solve(20=X(2),X)

i mean.. it should be 10 right?
but like it came up with the " memory error"

* I DID RESET MEMORY AND TRIED REINSTALLING OS <--lol
but none worked...

PLEASE TRY ON YOUR OWN CALCULATORS AND PLEASE HELP!!!!!!!

AGAIN PLEASE POST YOUR OWN RESULTS AFTER TRYING THE SAME EXACT EQUATION!!!

Hi 2Xist,

In the syntax of the TI-89, X(2) does not stand for multiplication of X and 2. That is the syntax for calling a user defined function X with a value of 2.

Instead try these

solve(20=x*2,x)

or

solve(20=2x,x)
