You can put this solution on YOUR website!
L = 20%
\n" ); document.write( "T = 50%
\n" ); document.write( "H= 80%
\n" ); document.write( "u = how much of L
\n" ); document.write( "v = how much of H
\n" ); document.write( "M=600 mililiters of the 50%.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28Lu%2BHv%29%2FM=T\" and \"u%2Bv=M\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve for u and v, since the system is two equation in two unknowns, u and v.
\n" ); document.write( "
