Let the youngest child's age be $\"a\"$
\n" ); document.write( "Their ages are then:
\n" ); document.write( " $\"a\"$ , $\"a+%2B+2\"$ , $\"a+%2B+4\"$ ,and $\"a+%2B+6\"$
\n" ); document.write( " $\"a+%2B+a+%2B+2+%2B+a+%2B+4+%2B+a+%2B+6+=+84\"$
\n" ); document.write( " $\"4a+%2B+12+=+84\"$
\n" ); document.write( " $\"4a+=+72\"$
\n" ); document.write( " $\"a+=+18\"$
\n" ); document.write( " $\"a+%2B+2+=+20\"$
\n" ); document.write( " $\"a+%2B+4+=+22\"$
\n" ); document.write( " $\"a+%2B+6+=+24\"$
\n" ); document.write( "Their ages are 18,20,22,and 24 \n" ); document.write( "
