This was on my 1.10 83-.  It didn't work so well, and I like the one on my 
89 better, but it was functional in a pinch (irritating that it made it 
equal to zero instead of the right side of the equation, so you have to set 
to zero like you have ther) 89 is nice because you can list out any number 
of equations, then an equal number of variables, and it will solve, then 
give the answer in fractional form. Does Symbolic so fractionals?
