(1) $\"P+=+V+-+4\"$
\n" ); document.write( "(2) $\"V+%2B+P+=+10\"$
\n" ); document.write( "Substitute (1) into (2)
\n" ); document.write( "(2) $\"V+%2B+V+-+4+=+10\"$
\n" ); document.write( " $\"2V+=+14\"$
\n" ); document.write( " $\"V+=+7\"$
\n" ); document.write( "and, since
\n" ); document.write( " $\"P+=+V+-+4\"$
\n" ); document.write( " $\"P+=+7+-+4\"$
\n" ); document.write( " $\"P+=+3\"$ \n" ); document.write( "
