TI's are pretty universal. If you look under the Calc menu which should be above trace (hence 2nd trace), you should find the intersect function as the 5th option.
Just did a google search and it looks like the 86 is a bit different. You might try this link:

For equation solving or substitutes for graphic calculators, Wolfram Alpha is a pretty good site (see KN's post). No need to install software.
My kids are using the TI-83 plus and that doesn't have the solver. We're stuck using the graphical approach that I posted earlier.
