Question 736806
Express EVERYTHING in symbols.


jeremy uses one cleanser that is L% acid and a second cleanser that is H% acid. How many liters of each as u and v must be mixed together to produce M liters that is T% acid?


The system of equations to start should or could be this:
{{{(Lu+Hv)/M=T}}} and {{{u+v=M}}}.
The unknown variables to find and solve for are u and v.


Do the steps which I am leaving out from this post, and you could get symbolic solutions as: {{{u=M*(H-T)/(H-L)}}} and {{{v=M-M*(H-T)/(H-L)}}}.


COMPUTING RESULTS
Just substitute the given values into the solution formulas.
