You can put this solution on YOUR website!
You didn't add any salt to the beaker,
\n" ); document.write( "so the 2% salt is still \"+.01%2A10+=+.1+\" kg
\n" ); document.write( "---------------------------------------
\n" ); document.write( "Let \"+x+\" = the total kg of the final mixture
\n" ); document.write( "\"+.1+%2F+x+=+.02+\"
\n" ); document.write( "\"+x+=+.1%2F.02+\"
\n" ); document.write( "\"+x+=+5+\"
\n" ); document.write( "\"+x+-+.1+=+5+-+.1+\"
\n" ); document.write( "\"+5+-+.1+=+4.9+\"
\n" ); document.write( "There is .1 kg of salt and
\n" ); document.write( "4.9 kg of water in the beaker after evaporation
\n" ); document.write( "--------------------------
\n" ); document.write( "There is 5 kg of salt water at this time
\n" ); document.write( "check the math\r
