Let X=one number, Y=the other number
\n" ); document.write( "X+Y=54
\n" ); document.write( "X-Y=18 Subtract Y from each side
\n" ); document.write( "X=Y+18 Substitute for X in first equation
\n" ); document.write( "(Y+18)+Y=54 Subtract 18 from each side
\n" ); document.write( "2Y=36 Divide each side by 2
\n" ); document.write( "Y=18
\n" ); document.write( "If X=Y+18,(equation above)
\n" ); document.write( "X=18+18=36
\n" ); document.write( "X=36 and Y=18, so:
\n" ); document.write( "X*Y=36*18=648 ANSWER: The product of the two numbers is 648.
\n" ); document.write( "CHECK
\n" ); document.write( "Sum=54
\n" ); document.write( "X+Y=54
\n" ); document.write( "36+18=54
\n" ); document.write( "54=54
\n" ); document.write( "Difference=18
\n" ); document.write( "X-Y=18
\n" ); document.write( "36-18=18
\n" ); document.write( "18=18
\n" ); document.write( "
\n" );
