You can put this solution on YOUR website!
0.10x + 0.60(50 - x) = 0.30*50
\n" ); document.write( "0.10x + 30 - 0.60x = 15,
\n" ); document.write( "-0.5x = -15,
\n" ); document.write( "x = 30, #ml of 10% solution,
\n" ); document.write( "50 - 30 = 20, #ml of 60% solution.
\n" ); document.write( "
\n" );
