To do this properly, you really need to know the density or specific gravity of each silver iodiDe solution. I assume you mean, "silver iodide", and not "silver iodine".

If you want to ignore density, you could proceed like this:

Let v = volume of the 10% silver iodide solution to use.
%288%2A4%2Bv%2A10%29%2F%288%2Bv%29=6
12%2B10v=6%28v%2B8%29
12%2B10v=6v%2B48
4v=36
v=9
Nine liters of the 10% solution to add.
