You can put this solution on YOUR website!
(y*0.2+x*0.05)/10=0.11
\n" ); document.write( "x+y=10\r
\n" ); document.write( "\n" ); document.write( "Where x cc of 5% solution, y cc of 20% solution.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Transform the rational equation to 20y+5x=10*11, divide by 5,
\n" ); document.write( "4y+x=22\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now you have the system
\n" ); document.write( "x+4y=22
\n" ); document.write( "x+y=10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract second equation from first equation and obtain 3y=12, then y=4.
\n" ); document.write( "Since \"highlight%28y=4%29\", \"highlight%28x=6%29\".
\n" ); document.write( "
\n" );
