Let $\"+a+\"$ = Lea's age now
\n" ); document.write( "Let $\"+b+\"$ = Cherry's age now
\n" ); document.write( "---------------------------
\n" ); document.write( " $\"+a+%2B+5+\"$ = Lea's age in 5 yrs
\n" ); document.write( " $\"+b+%2B+5+\"$ = Cherry's age in 5 yrs
\n" ); document.write( "------------------------------
\n" ); document.write( "(1) $\"+a+=+6b+%2B+5+\"$
\n" ); document.write( "(2) $\"+a+%2B+5+=+4%2A%28+b+%2B+5+%29+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "(1) $\"+a+-+6b+=+5+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+a+%2B+5+=+4b+%2B+20+\"$
\n" ); document.write( "(2) $\"+a+-+4b+=+15+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "Subtract (1) from (2)
\n" ); document.write( "(2) $\"+a+-+4b+=+15+\"$
\n" ); document.write( "(1) $\"+-a+%2B+6b+=+-5+\"$
\n" ); document.write( " $\"+2b+=+10+\"$
\n" ); document.write( " $\"+b+=+5+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+a+=+6b+%2B+5+\"$
\n" ); document.write( "(1) $\"+a+=+6%2A5+%2B+5+\"$
\n" ); document.write( "(1) $\"+a+=+35+\"$
\n" ); document.write( "--------------
\n" ); document.write( "Lea is 35 and Cherry is 5
