Q: I am needing to know how to solve three variable equations on my TI-83 calculator and have not had any luck trying to figure it out myself.
A: You could try using the [Math] > 0:Solver...
Let's say the problem was 2x + 3y − 7z = 6. In the Solver, you would have to put 0=2X+3Y−7Z−6.
From then on it's mainly just guessing-and-checking each value of x, y,

It has built in Financial Apps, which is a nice addition (and helpful!) compared to the 82 (which it is also compatible with!). But the 89? Even the 85? They take greater than calculus students to even need/use those functions, and they are a much harder to learn calculator. The Calculus teacher at our school says that the 83 will get you all through calculus and most likely beyond college. My calculator, which is really easy to learn, came in handy the first day in Geometry. We had to figure an area of a wierd shape and we only had the co-ordinates, i punched them in, and POW, found the area. If you do get this calculator, a TI-Graph Link is a must, this allows you to download software and…
