You can put this solution on YOUR website!
Is \"y\" on the bottom or the top of the fraction ?
\n" ); document.write( "If it's on the top, you have:
\n" ); document.write( "\"+%282%2F5%29%2Ay+=+4%2F5+\"
\n" ); document.write( "----------------
\n" ); document.write( "The rule is: Whatever you do to one side of the
\n" ); document.write( "equals sign, you must do to the other side, and the
\n" ); document.write( "equation will still be true.
\n" ); document.write( "----------------
\n" ); document.write( "First multiply both sides by \"5\"
\n" ); document.write( "Then what you have is:
\n" ); document.write( "\"+%285%2F5%29%2A2y+=+%285%2F5%29%2A4+\"
\n" ); document.write( "\"+2y+=+4+\"
\n" ); document.write( "Divide both sides by \"+2+\"
\n" ); document.write( "\"+%282%2F2%29%2Ay+=+4%2F2+\"
\n" ); document.write( "\"+y+=+2+\" answer
\n" ); document.write( "===================
\n" ); document.write( "Now if the \"y\" is on the bottom of the fraction,
\n" ); document.write( "Multiply both sides by \"5\" also
\n" ); document.write( "\"+%285%2F5%29%2A%282%2Fy%29+=+%285%2F5%29%2A4+\"
\n" ); document.write( "\"+2%2Fy+=+4+\"
\n" ); document.write( "Now multiply both sides by \"y\"
\n" ); document.write( "\"+%28y%2Fy%29%2A2+=+4y+\"
\n" ); document.write( "\"+2+=+4y+\"
\n" ); document.write( "Divide both sides by \"4\"
\n" ); document.write( "\"+y+=+2%2F4+\"
\n" ); document.write( "\"+y+=+1%2F2+\"
\n" ); document.write( "----------
\n" ); document.write( "Hope this helps
