Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
H = 12% HCl
L = 6% HCl
T = 10% HCl
M = 24 oz.
u = ounces of 6% HCl, unknown
v = ounces of 12% HCl, unknown

and

Solve the system for u and v. Doing everything in symbols first, means you have then solved ALL two-part mixture problems of this type. This particular 24 ounce HCl from your given starting values is only one example.

Once formulas for u and v are found, just plug in the given values to find your final results.
