Which of the following describes the correct process for solving the equation 3x + 6 = 21 and arrives at the correct solution?

Divide both sides by 6 and then add 3. The solution is x = 5.

Add 6 to both sides of the equation and then divide by 3. The solution is x = 9.

Subtract 6 from both sides of the equation and then divide by 3. The solution is x = 8.

Subtract 6 from both sides of the equation and then divide by 3. The solution is x = 5.
