You can put this solution on YOUR website!
Assign some variables to everyting.\r
\n" ); document.write( "\n" ); document.write( "M=600 ml. result solution
\n" ); document.write( "u= volume of 35% solution
\n" ); document.write( "v = volume of 60% solution
\n" ); document.write( "T = 45% solution wanted
\n" ); document.write( "L = 35%
\n" ); document.write( "H = 60%
\n" ); document.write( "You want to find u and v.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The concentration equation symbolically can begin as \"%28Lu%2BHv%29%2F%28u%2Bv%29=T\".
\n" ); document.write( "Also fact is u+v=M. Solve this simpler one for v, to have v=M-u; substitute this into the rational equation, solve for u, and you will have, after algebraic steps:
\n" ); document.write( "\"highlight%28u=M%28H-T%29%2F%28H-L%29%29\", substitute the given values to find value for u, and then go back to \"highlight%28v=M-u%29\" and get the value for v.\r
