xy=48
\n" ); document.write( "x=y/3
\n" ); document.write( "y/3*y=48
\n" ); document.write( "y^2/3=48
\n" ); document.write( "y^2=3*48
\n" ); document.write( "y^2=144
\n" ); document.write( "y=sqrt144
\n" ); document.write( "y=12 ans.
\n" ); document.write( "x=12/3
\n" ); document.write( "x=4 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "4*12=48
