X/4=X/7+3
\n" ); document.write( "X/4-X/7=3
\n" ); document.write( "(7X-4X)/4*7)=3
\n" ); document.write( "3X/28=3 CROSS MULTIPLY.
\n" ); document.write( "3X=28*3
\n" ); document.write( "3X=84
\n" ); document.write( "X=84/3
\n" ); document.write( "X=28 IS THE NUMBER.
\n" ); document.write( "PROOF:
\n" ); document.write( "28/4=28/7+3
\n" ); document.write( "7=4+3
\n" ); document.write( "7=7
