Let $\"n\"$ = the number of years from now when
\n" ); document.write( "Rose will be twice as old as Peggy
\n" ); document.write( " $\"4+%2B+n\"$ will be Peggy's age then
\n" ); document.write( " $\"10+%2B+n\"$ will be Rose's age then
\n" ); document.write( "given:
\n" ); document.write( " $\"10+%2B+n+=+2%2A%284+%2B+n%29\"$
\n" ); document.write( " $\"10+%2B+n+=+8+%2B+2n\"$
\n" ); document.write( "Subtract $\"8\"$ from both sides
\n" ); document.write( " $\"2+%2B+n+=+2n\"$
\n" ); document.write( " $\"n+=+2\"$
\n" ); document.write( "In 2 years, Rose will be twice as old as Peggy
\n" ); document.write( "check:
\n" ); document.write( " $\"10+%2B+n+=+2%2A%284+%2B+n%29\"$
\n" ); document.write( " $\"10+%2B+2+=+2%2A%284+%2B+2%29\"$
\n" ); document.write( " $\"12+=+2%2A6\"$
\n" ); document.write( " $\"12+=+12\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
