Let the first number = x.
\n" ); document.write( "Then the other number = 12 more than 'x' = (x+12).\r
\n" ); document.write( "\n" ); document.write( "Clearly, 'x' is the smaller number and (x+12) is the larger.
\n" ); document.write( "So the sum of the smaller number and twice the larger number = x + 2(x + 12) = 39
\n" ); document.write( "i.e. x + 2(x + 12) = 39
\n" ); document.write( "x + 2x + 2*12 = 39
\n" ); document.write( "3x + 24 = 39
\n" ); document.write( "3x = 39 - 24
\n" ); document.write( "3x = 15
\n" ); document.write( "x = 15/3
\n" ); document.write( "x = 5\r
\n" ); document.write( "\n" ); document.write( "So the smaller number = x = 5 and the larger number = (x + 12) = 5 + 12 = 17\r
\n" ); document.write( "
