After x years, Sam's age will be x + 20, and Carl's age will be x + 6.\r
\n" ); document.write( "\n" ); document.write( "At that time, Sam will be twice as old as Carl.\r
\n" ); document.write( "\n" ); document.write( "i.e. \"x+%2B+20+=+2%2A%28x+%2B+6%29\"
\n" ); document.write( "\"x+%2B+20+=+2%2Ax+%2B+12\"
\n" ); document.write( "Simplifying, \"x+=+8\"\r
\n" ); document.write( "\n" ); document.write( "After 8 years, Sam will be twice as old as Carl.
\n" ); document.write( "Check: After 8 years, Carl's age will be 6+8 = 14 and Sam's age will be 20+8 = 28.
\n" ); document.write( "28 is twice 14. Correct!\r
