Select ALL the answers that apply. A student is solving the equation 21 y + 3) = 14 for y. Which of these could be the next step?

1. Distribute on the left hand side to get 2y +3 = 14
2. Divide both sides by 2 to get y+3 = 7
3. Distribute on the left hand side to get 2y +6 = 14
4. Subtract 3 from both sides to get 2y = 11
5. Divide both sides by 2 to get y+3 = 14
