I have a TI-89 titanium calculator. I am trying to use the solve() function under the algebra menu to solve multiple equations. What is the format for entering the equations and the variables?
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.
