let one number be x
\n" ); document.write( "the other number will be 1200-x. ( Because the sum of both is 1200)
\n" ); document.write( "..
\n" ); document.write( "one number is 800 less than the 3 times the other.
\n" ); document.write( "The other number is 1200-x
\n" ); document.write( "3 times other = 3(1200-x)
\n" ); document.write( "less 800
\n" ); document.write( "= 3(1200-x) -800
\n" ); document.write( "x=3(1200-x)-800
\n" ); document.write( "x=3600-3x-800
\n" ); document.write( "x+3x= 2400
\n" ); document.write( "4x = 2400
\n" ); document.write( "divide by 4
\n" ); document.write( "x= 2400/4
\n" ); document.write( "x=600
\n" ); document.write( "if one number is 600, then other is 1200-x=600.
\n" ); document.write( "
\n" );
