Hello,
Here are screen captures to helps you set up your graphs. Notice the highlighted = sign. If there is no highlighting on the = sign the curve is not drawn. Highlight a sign and press [ENTER]

Here are the graphs. Functions are as in setup.

To change the style of the curve, left arrow to the left of the letter Y and press [ENTER]. Every time you press [ENTER] the style changes. Beware there is one in the form of an unconnected bubble. While you see the bubble when a point is being drawn, the whole curve will evaporate at the end.
Hope it helps.

### 2c + 6 + 7c = 8

To solve this with a ti-84 press [math] and select solve from the menu. This will open the equation solver. Type in your equation
(Note: you may need to put it in the form with 0=, So the equation would be 0 = 2c + 6 +7c - 8 ). Then press
enter or arrow down button.

### My ti-84 is only graphing one linear equation in the y equal when i put two equations in it only show one

When you enter a function you should press [ENTER] to validate. At the same time, the cursor moves to the next line. Verify that the = sign on the equation already entered is still highlighted.
If for some reason the = sign of an equation is no longer highlighted, use arrow keys to move cursor on the = sign and press [ENTER].

If only one = sign remains highlighted and all others are not, then in all probability the application Transfrm has been executed before and is still lingering in RAM. When in RAM, it takes over the graphing capabilities of the native OS. This prevents you from drawing more than one graph.You must unload it from memory.
1. Press the [APPS] key.
2. Scroll down to the line that shows Transfrm.
3. Highlight it and press [ENTER].
4. In following screen you are invited to Uninstall or continue.
5. Press the number to the left of Uninstall. Validate if need be.
6. Return to the Y= editor to type in functions to graph.

### My TI--84 plus calculator won't display the 7 graph modes, and it won't graph equations simultaneously. What is wrong? I can only get an arrow icon and an arrow-bar icon.

Hello,
Use the [Y=] entry screen to enter the functions you want to graph. Make sure that the = sign after Y1, Y2 etc. is highlighted (black). If the = sign is not highlighted the corresponding function will not be drawn. You can can up to 10 functions, but what is the point of drawing so many if they overlap?
Anyway, to change the graph style of the curve for a particular function, use arrows to move to the line, then use left arrow to the bit of line that appears to the left of the Y. Highlight the segment an press ENTER. Each time you press ENTER the style changes to another one. Beware of the unconnected bubble style. During the drawing it will show the position of the point being drawn, but at the end, the whole curve, so to speak, evaporates.
As to simultaneous graphs, if it is important to you to have the graphs drawn for all the curves at the same time, you can enforce that by pressing [MODE], and using down arrow to reach the 6th line Sequential Simul. Use the right arrow to highlight Simul and press ENTER.
Whether drawn sequentially or simultaneously, all graphs will be displayed, except for the ones with the unconnected bubble as style.

Hope it helps.

### How do i solve this problem 3x+25=5x using my TI 84 plus

i think there are programs but with something as simple as that you should be able to work it out manually....
3x+25-5x=5x-5x
-2x+25-25=0-25
-2x=-25
x=25/2 or 12.5
