SOURCE: Graph feature is not working on TI-83

you have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck

Hello,
What do you want to do with it? If you want just to enter it, you do so on the command line.
Here are exemples of solutions
Under [Mode][F2] exact/aprox set to exact
solve(x^2+x-5=0,x) finds the exact solutions the top ones


Under [MODE][F2] Exact/Aprox set to Approximate you get approximate numerical solutions, the bottom ones.
There is another command nSolve( which solves numerically for an equation. You can specify a range of values where solution is suspected to be.

Hope it helps

SOURCE: solving multiple non-linear equations

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.
