Let $\"+a+\"$ = your age now
\n" ); document.write( "Let $\"+b+\"$ = your brother's age now
\n" ); document.write( "---------------
\n" ); document.write( "(1) $\"+a+=+b+%2B+4+\"$
\n" ); document.write( "(2) $\"+a+-+2+=+%283%2F2%29%2A%28+b-2+%29+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "(2) $\"+2a+-+4+=+3b+-+6+\"$
\n" ); document.write( "(2) $\"+2a+-+3b+=+-2+\"$
\n" ); document.write( "(2) $\"+-2a+%2B+3b+=+2+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+a+-+b+=+4+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "Multiply both sides of (1) by $\"2\"$
\n" ); document.write( "and add (1) and (2)
\n" ); document.write( "(2) $\"+-2a+%2B+3b+=+2+\"$
\n" ); document.write( "(1) $\"+2a+-+2b+=+8+\"$
\n" ); document.write( " $\"+b+=+10+\"$
\n" ); document.write( "and

\n" ); document.write( "(1) $\"+a+=+10+%2B+4+\"$
\n" ); document.write( "(1) $\"+a+=+14+\"$
