The description is not specific. "Pure rubbing alcohol" does not mean anything precise. It is not pure alcohol, concentrations vary depending on the supplier companies product decisions. Do you want to assume 70% of "alcohol"?

You might be looking for something this way:

x, how much of the 10% alcohol to add.
y, how much "rubbing alcohol".

system%28%2810%2Ax%2B70%2Ay%29%2F16=14%2Cx%2By=16%29.

Solve for x and y.
