\n" ); document.write( "PROOF:
\n" ); document.write( "(7-3)/7=4/7
\n" ); document.write( "4/7=4/7

\n" ); document.write( "IF YOU MEAN X-(3/X)=4/7 THEN:
\n" ); document.write( "(X^2-3)/X=4/7 CROSS MULTIPLY
\n" ); document.write( "7(X^2-3)=4X
\n" ); document.write( "7X^2-21-4X=0
\n" ); document.write( "7X^2-4X-21=0
