I have no idea what \"LEWAC\" is but I
\n" ); document.write( "can solve the problem
\n" ); document.write( "Let $\"p\"$ = Phil's age now
\n" ); document.write( "Let $\"s\"$ = Stanley's age now
\n" ); document.write( "(1) $\"p+=+s+%2B+24\"$
\n" ); document.write( "(2) $\"p+-+4+=+7%2A%28s+-+4%29\"$
\n" ); document.write( "Substitute $\"p\"$ in (1) for $\"p\"$ in (2)
\n" ); document.write( " $\"s+%2B+24+-+4+=+7s+-+28\"$
\n" ); document.write( " $\"6s+=+20+%2B+28\"$
\n" ); document.write( " $\"6s+=+48\"$
\n" ); document.write( " $\"s+=+8\"$
\n" ); document.write( " $\"p+=+s+%2B+24\"$
\n" ); document.write( " $\"p+=+32\"$
\n" ); document.write( "Presently, Phil is 32 and Stanley is 8
\n" ); document.write( "check:
\n" ); document.write( "(2) $\"p+-+4+=+7%2A%28s+-+4%29\"$
\n" ); document.write( " $\"32+-+4+=+7%2A%288+-+4%29\"$
\n" ); document.write( " $\"28+=+7%2A4\"$
\n" ); document.write( " $\"28+=+28\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
