Here how it is done. Don't mind the calculator it was done on. On your you may have systems of up to 3 linear equations.

Pressing the F1 key on the last screen allows you to repaet with the same or different coefficients.

Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
New users get to try the service completely Free afterwhich it costs \$6 per call and covers almost anything you can think of (from cars to computers, handyman, and even drones).
Goodluck!

SOURCE: @ symbol

According to the TI-89 Guidebook:

This notation indicates an “arbitrary integer” that represents any integer. When an arbitrary integer occurs multiple times in the same session, each occurrence is numbered consecutively. After it reaches 255, arbitrary integer consecutive numbering restarts at @n0.

SOURCE: i do not know how

Hey it is. Okay, so start with a equation: say, y = -(1 |x|). Now type y = -(1 , then press the [OPTN] button, next to the shift. Next press the [NUM] button or F5. The first menu button should be Abs or absolute value. When your done it should look like this. y = -(1 Abs (x)) then graph it.

### How should I set the v-window when I enter my distance equation?

The Window parameters control the width and length of the graphing screen. The distance equation is a formula to use to calculate the distance between two points known by their coordinates. The window dimensions have nothing to do with calculations. Or maybe I don't understand the question.

### How to predict using linear model

If you have the equation of the line (of best fit), enter a value of x in the equation to get the value of y. Similarly, if you have a target value of y, enter it in the equation and solve for the value of x. That's about it.

### How can i solve tree equations with fx 4500p

Do you mean three (3) linear equations in 3 unknowns, or tree allometric equations? Thank you Al Gore for inventing the Internet.
For the second case, we really need to know the form of the functions in view of their graphical representation:
Since this calculator cannot do graphs, you can generate a table of values and then represent the variation on graphing paper (linear or logarithmique) depending on the form of the dependence.
Here is a link to the user's manual for this calculator.

Follow the screen captures. I do not think any additional comments are warranted. Pressing the F1 key (REPT)-- see last screen capture--allows the user to repeat the solution with the same coefficients or other ones (different system)

### How to solve equations with two variables by usin CASIO fx901 calculater? eg- 6x+9y=2700 5x+4y=1560

The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver.
You cannot use it to solve equations.
Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991.
Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.

Hello,
I do not understand what you mean by solve complex equations, but if you want to manipulate complex numbers here are the tools you need to enter your complex numbers. Operations and function evaluations do not need special symbols.

Hope it helps.
