Elaine sold three times as many magazines as Ron. Ron sold 16 less magazines than elaine. How many magazines did they both sell?

x = Ron's sales

3x = Elaine's sales {Elaine sold three times as many as Ron}

x = 3x - 16 {Ron sold 16 less than Elaine}

-2x = -16 {subtracted 3x from both sides}

x = 8 {divided both sides by -2}

3x = 24 {substituted 8, in for x, into 3x}

**Ron sold 8 and Elaine sold 24**
