one number is twice another number.
\n" ); document.write( "a = 2b
\n" ); document.write( "if 15 is subtracted from both the numbers,the one of the new numbers become trice that of new number.
\n" ); document.write( "a - 15 = 3(b - 15)
\n" ); document.write( "a - 15 = 3b - 45
\n" ); document.write( "a = 3b - 45 + 15
\n" ); document.write( "a = 3b - 30
\n" ); document.write( "replace a with 2b
\n" ); document.write( "2b = 3b - 30
\n" ); document.write( "30 = 3b - 2b
\n" ); document.write( "30 = b
\n" ); document.write( ":
\n" ); document.write( "one number (b) is 30 and the other number, obviously is 60\r
