Srry my friend the ti 83 is no magnificent Ti-89. meaning: you have to solve it yourself. There is a method for graphing though. Set the equation equal to zero and then plug the stuff on the other side of the equation into a graph by pressing y= and then typing it in. Then hit graph. Wait for the graph and then hit 2nd calc and select zeros. Bring your cursor using hte arrow keys close to where the line hits the x axis and press enter and then do the same except to the right of that point and then press enter twice and it will display the y which should be the answer
There are quadratic formulas for calculators programmed in tibasic for the calc but other than that there is no way to solve it

Find the antilog on the TI-83 Plus for finding pH in chemistry problems


I reccently had the same problem, but I have a Ti-84 Plus,and I am disgusted by how poorly this matter is covered by Texas Intruments. Esp. since the solution is rather simple.

The antilog key is [2nd] [log] or the 10^x. On your screen it should apear as 10^( and then you just input the value that you want to find the antilog of.

When used to solve pH problems remember to input the pH value as a negative number, since pH= -log[H+] then [H+]= antilog(-pH).

Hope that helped))))) ^^
