Solutions and Ksp

a 1.924 L solution is made by dissolving 6.432g of Li3PO4 into water. Calculate the concentrations of the ions present when the Li3PO4 solution is added to 1.598 L of an Ag3PO4 solution.

 

So, I can calculate the concentrations of each ion in the separate solutions and in the combined solution, but then I think that if something precipitates, the concentrations would change. According to my calculations, the calculated Ksp of Ag3PO4 exceeds the real Ksp of saturation for the solution. This would mean a precipitate of Ag3PO4. From there, I am lost. I don't know how to calculate how much precipitates and whether I should subtract the precipitated solid from the concentrations I calculated. Please help!
