Let $\"g\"$ = Gita's age now
\n" ); document.write( "Let $\"m\"$ = Mother's age now
\n" ); document.write( "-------------
\n" ); document.write( "Given:
\n" ); document.write( " $\"g+=+%281%2F3%29%2Am\"$
\n" ); document.write( " $\"g+%2B+12+=+%281%2F2%29%2A%28m+%2B+12%29\"$
\n" ); document.write( "Substituting:
\n" ); document.write( " $\"%281%2F3%29%2Am+%2B+12+=+%281%2F2%29%2Am+%2B+%281%2F2%29%2A12\"$
\n" ); document.write( " $\"%281%2F2%29%2Am+-+%281%2F3%29%2Am+=+-6+%2B+12\"$
\n" ); document.write( "Multiply both sides by $\"6\"$
\n" ); document.write( " $\"3m+-+2m+=+36\"$
\n" ); document.write( " $\"m+=+36\"$
\n" ); document.write( "and
\n" ); document.write( " $\"g+=+%281%2F3%29%2Am\"$
\n" ); document.write( " $\"g+=+36%2F3\"$
\n" ); document.write( " $\"g+=+12\"$
\n" ); document.write( "Gita is presently 12, and her Mother
\n" ); document.write( "is presently 36
\n" ); document.write( " \n" ); document.write( "

\n" );
