Two numbers, one is 20 more than the other
\n" ); document.write( "X is the larger number, the other is X-20
\n" ); document.write( "The sum of the two numbers is 400
\n" ); document.write( "X+(X-20)=400
\n" ); document.write( "2X-20=400 Add 20 to each side
\n" ); document.write( "2X-20-+20=400+20
\n" ); document.write( "2X=420 divide both sides by 2
\n" ); document.write( "X=210 ANSWER the larger number is 210
\n" ); document.write( "CHECK:
\n" ); document.write( "the smaller number is 20 less
\n" ); document.write( "small=210-20=190
\n" ); document.write( "sum is 400: smaller+larger=400
\n" ); document.write( "190+210=400
\n" ); document.write( "400=400
\n" ); document.write( "
