Let $\"+n+\"$ = number of years until
\n" ); document.write( "dad is twice as old as Pam
\n" ); document.write( "------------------------
\n" ); document.write( " $\"+37+%2B+n+=+2%2A%28+14+%2B+n+%29+\"$
\n" ); document.write( " $\"+37+%2B+n+=+28+%2B+2n+\"$
\n" ); document.write( "Subtract $\"+28+\"$ from both sides
\n" ); document.write( " $\"+9+%2B+n+=+2n+\"$
\n" ); document.write( "Subtract $\"+n+\"$ from both sides
\n" ); document.write( " $\"+9+=+n+\"$
\n" ); document.write( "In 9 yrs, Pam's dad is twice Pam's age
\n" ); document.write( "------------------
\n" ); document.write( "check:
\n" ); document.write( "In 9 yrs, Pam is: $\"+14+%2B+9+=+23+\"$
\n" ); document.write( "In 9 yrs, Pam's dad is: $\"+37+%2B+9+=+46+\"$
\n" ); document.write( " $\"+46+=+2%2A23+\"$
\n" ); document.write( "OK \n" ); document.write( "
