Press Y=
On the Y1 line enter the expression LOG(X+2)+LOG(X+3) by pressing
LOG ALPHA [X] ) + LOG ALPHA [X] + 3 )
On the Y2 line enter the expression 7-X by pressing
7 - ALPHA [X]
Press GRAPH to see the graph. To see where they intersect, press 2ND [CALC] 5. See "First curve?" in the lower left. Use up/down-arrow to select one of the two curves and press ENTER. See "Second curve?" in the lower left. Use up/down-arrow to select the other curve and press ENTER. See "Guess?" in the lower left. Press ENTER. The calculator will show the coordinates of the intersection.

This is my first post on this site, but I've had friends at school ask me about this. Apparently I'm like a calculator genius or something...
One solution I know of is clearing the RAM. Sounds strange, doesn't it? But it fixed three different calcs.
Be sure to back up or archive important data before doing this.

The calculator only displays from -10 to 10 on the x and y axes, and both of your lines are outside of that range. However, it is easy to change that.
1. Hit the gray "WINDOW" button that is directly under the screen
2. Change "Xmax" to 150
3. Change "Ymax" to 200
Remember to change both of those values back to 10 when you are done with this problem!
Here's how to graph it:
1. Hit the "Y=" button
2. Enter your first equation after Y1, and your second equation after Y2
3. Look over both the equations to make sure you typed them correctly
4. Hit the "GRAPH" button
5. If you don't see the intersection you will need to adjust Xmax and Ymax again
6. Hit Hit "2ND" and the "TRACE" to bring up the "CALC" menu
7. Scroll down to "intersect" and hit enter
8. Hit enter 3 times (You use the first and second curve options when you have more than 2 lines)
9. It should display the coordinates at the bottom
10. I got (76, 142.1) for the intersection
Thanks for asking this question! I used to do this a much harder way, but while I was calculating the answer to your question I hit a wrong button and accidentally found this method!

Hi,
There 4 or 5 programs for the TI83/4Plus family of calculators available at ticlac.org. Scroll down the page to find them. Download them and transfert to your calculator using TIConnectivity software.
Hope it helps.
Thank you for using fixYa and for rating the solution.
SOURCE: how to simplify the equations in ti 84 ??
You cannot do it with this calculator. It does not have a Computer Algebra System (CAS). Try a TI89 Titanium, a TI 92PLUS, a TI 200PLT or a TI-Nspire CAS.
However, they may exist other programs on education.ti.com or ticalc.org. Search these sites and you may be lucky.

SOURCE: Change TI 84 OS to TI 89 OS??
And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or amazon.com and spare your TI84PLus SE.
