Question 753913
A physicist needs M liters of a T% acid solution.  He has a L% acid solution and a H% acid solution.  How many liters of each L% and H% does he need to total M liters of a T% acid solution?


{{{L<T<H}}}

Let u = liters of L%
Let v = liters of H%


{{{(Lu+Hv)/M=T}}} and {{{u+v=M}}}
The only unknowns are u and v.  Solve this system for u and v.
