Answer:

Charlie's solution is incorrect.

Part A: The equation must be divided by the number next to the variable. So 5x will be divided by 5 which will equal x, and 30 will be divided by 5 which equals 6. The final answer will be x=6.

Part B: The equation will have one solution because there is only one way to solve it.
