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( " |
