\n" ); document.write( "(1) $\"+a+-+1+=+3%2A%28+b+-+1+%29+\"$
\n" ); document.write( "(2) $\"+a+=+2b+\"$
\n" ); document.write( "-------------------
\n" ); document.write( "Substitute (2) into (1)
\n" ); document.write( "(1) $\"+2b+-+1+=+3%2A%28+b+-+1+%29+\"$
\n" ); document.write( "(1) $\"+2b+-+1+=+3b+-+3+\"$
\n" ); document.write( "(1) $\"+b+=+2+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+a+=+2b+\"$
