Let $\"+c+\"$ = cost of the cat
\n" ); document.write( "Let $\"+d+\"$ = cost of the dog
\n" ); document.write( "--------------
\n" ); document.write( "(1) $\"+c+=+%281%2F3%29%2Ad+\"$
\n" ); document.write( "(2) $\"+c+%2B+d+=+220+\"$
\n" ); document.write( "----------------
\n" ); document.write( "(1) $\"+d+=+3c+\"$
\n" ); document.write( "by substitution:
\n" ); document.write( "(2) $\"+c+%2B+3c+=+220+\"$
\n" ); document.write( "(2) $\"+4c+=+220+\"$
\n" ); document.write( "(2) $\"+c+=+55+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+d+=+3%2A55+\"$
\n" ); document.write( "(1) $\"+d+=+165+\"$
\n" ); document.write( "----------------
\n" ); document.write( "The cat costs $55
\n" ); document.write( "The dog costs $165\r
