Really is the same as the other one you posted.....

Answer: Kevin sold 63 books.

Solution:

Let J be the number of books Jacob sold. Let K be the number of books Kevin sold. Let M be the number of books Miguel sold.

J + K + M = 328

M = J + 55

J = K + 42

Substition:

J + K + J + 55 = 328

3K + 139 = 328

3K = 189

K = 63
