Stacy has 32 berries. Steve takes 4 of Stacy's berries, and still has 7 less berries than Stacy started with. How many berries did Steve start with? Give me reasons, before answering the question

Let x be the number of berries Steve started with. x + 4 = 32 - 7. x + 4 = 25. x = 21 berries. So the final answer is 21.
