x+y=38, x=38-y
\n" ); document.write( "-----------------
\n" ); document.write( "175000x+200000y=7200000
\n" ); document.write( "----------------------
\n" ); document.write( "175000(38-y)+200000y=7200000
\n" ); document.write( "6650000-175000y+200000y=7200000
\n" ); document.write( "25000y=550000
\n" ); document.write( "y=22 more expensive
\n" ); document.write( "x=16 cheaper house
\n" ); document.write( "----------------------------------
\n" ); document.write( "22*200000=4400000
\n" ); document.write( "16*175000=2800000
\n" ); document.write( "
\n" ); document.write( "
