Let Carl's age = C
\n" ); document.write( "Let Lyn's age = L\r
\n" ); document.write( "\n" ); document.write( "Carl is 3 years older than Lyn
\n" ); document.write( "C = L + 3 ...eqn. (1)\r
\n" ); document.write( "\n" ); document.write( "In five years,
\n" ); document.write( "Carl's age = C + 5
\n" ); document.write( "Lyn's age = L + 5
\n" ); document.write( "The sum of their ages is 67
\n" ); document.write( "(C + 5) + (L + 5) = 67
\n" ); document.write( "C + 5 + L + 5 = 67
\n" ); document.write( "C + L + 10 = 67
\n" ); document.write( "C + L = 57 ...eqn. (2)\r
\n" ); document.write( "\n" ); document.write( "Subst. (L + 3) for C in eqn. (2)
\n" ); document.write( "L + 3 + L = 57
\n" ); document.write( "2L = 54
\n" ); document.write( "L = 27\r
\n" ); document.write( "\n" ); document.write( "Subst. 27 for L in eqn. (1)
\n" ); document.write( "C = 27 + 3
\n" ); document.write( "C = 30\r
\n" ); document.write( "\n" ); document.write( "Carl is 30 years old; Lyn is 27 years old
\n" ); document.write( " \n" ); document.write( "
\n" );
