Let the number of mailboxes Mr. Ruiz started with be ( x ). After selling 5 mailboxes, he had ( x - 5 ). Then he made 12 more, giving him ( x - 5 + 12 = x + 7 ). We know he now has 15 mailboxes, so we can set up the equation ( x + 7 = 15 ). Solving for ( x ), we find that he started with ( x = 8 ) mailboxes.
