You can put this solution on YOUR website!
0.95*1 + 0.00*x = 0.50(1+x)\r
\n" ); document.write( "\n" ); document.write( "==> 0.95 = 0.50 + 0.50x\r
\n" ); document.write( "\n" ); document.write( "==> 0.45 = 0.50x\r
\n" ); document.write( "\n" ); document.write( "==> x = 0.9 liters of water should be added.
