You can put this solution on YOUR website!
Let \"+x+\" = ml of solution B needed
\n" ); document.write( "\"+x+-+500+\" = ml of solution A used
\n" ); document.write( "-------------------------------
\n" ); document.write( "\"+.17x+%2B+.2%2A%28+x+-+500+%29+=+492+\"
\n" ); document.write( "\"+.17x+%2B+.2x+-+100+=+492+\"
\n" ); document.write( "\"+.37x+=+592+\"
\n" ); document.write( "\"+x+=+1600+\"
\n" ); document.write( "She uses 1600 ml of solution B
\n" ); document.write( "------------------
\n" ); document.write( "check:
\n" ); document.write( "\"+.17x+%2B+.2%2A%28+x+-+500+%29+=+492+\"
\n" ); document.write( "\"+.17%2A1600+%2B+.2%2A%28+1600+-+500+%29+=+492+\"
\n" ); document.write( "\"+272+%2B+.2%2A1100+=+492+\"
\n" ); document.write( "\"+272+%2B+220+=+492+\"
\n" ); document.write( "\"+492+=+492+\"
\n" ); document.write( "OK
\n" ); document.write( "
