Let $\"+a+\"$ = Linda's age now
\n" ); document.write( "Let $\"+b+\"$ = Jane's age now
\n" ); document.write( "given:
\n" ); document.write( "(1) $\"+a+=+2b+%2B+3+\"$
\n" ); document.write( "(2) $\"+a+%2B+5+%2B+b+%2B+5++=+28+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "From (1)
\n" ); document.write( "(1) $\"+a+-+2b+=+3+\"$
\n" ); document.write( "From (2)
\n" ); document.write( "(2) $\"+a+%2B+b+=+18+\"$
\n" ); document.write( "Subtract (1) from (2)
\n" ); document.write( "(2) $\"+a+%2B+b+=+18+\"$
\n" ); document.write( "(1) $\"+-a+%2B+2b+=+-3+\"$
\n" ); document.write( " $\"+3b+=+15+\"$
\n" ); document.write( " $\"+b+=+5+\"$
\n" ); document.write( "And, since
\n" ); document.write( "(2) $\"+a+%2B+b+=+18+\"$
