16. 2(h – 8) – h = h – 16

17. 3 + 6z = 13 + 6z

18. Angela and Neil are going to the movies. They each bought a medium popcorn, and Neil got a small soft drink. Angela had a $5 gift certificate to put toward the cost, and Neil paid the rest, which came to $27.90. A movie ticket costs $10.00, and a medium popcorn costs $5.50. How much does a soft drink cost at the theater?

19. 3(y – 5) + 2 = 5 __ 20. 70 = –7(–2 – 2z)

21. –6p + 7 = 3(2p – 3) – 4(–10 + 4p)
