A carnival performer claims to be able to guess a person's weight within 4lbs of their actual weight or the person wins a prize. If a person weighs 142lbs, which equation can be used to find the minimum and maximum weights the performer can guess without the person winning a prize?

• |x - 142| = 4

• |x - 4| = 142

• |x + 4| = 142

• |x + 142| = 4
