x = second number
\n" ); document.write( "2x = first number
\n" ); document.write( "2x + x = 30
\n" ); document.write( "3x = 30
\n" ); document.write( "3x/3 = 30/3
\n" ); document.write( "x = 10
\n" ); document.write( "Therefore 2x = 2(10) = 20
\n" ); document.write( "So the numbers are 10 and 20
\n" ); document.write( "
