将 Fbox 左对齐

Question

我正在尝试为我的数学答题册设置空间。我想将框对齐到页面左侧，但当我使用\parts或时\enumerate对齐会发生变化。我想使用整个页面的宽度，而不管问题类型如何。请不要介意这个问题。我只需要格式方面的帮助。

Answer 1

我在我的列表示例集合中找到了以下解决方案。由于您没有提供姆韦（最小工作示例）我对你的文档一无所知，因此采用以下内容姆韦根据您的需要我留给您：

编辑： 现在，当了解有关您的文档的更多信息时，我将采用我对您的文档的原始答复。在此我做了以下事情：

• 重新组织您的文档序言（您真的需要所有加载的软件包吗？）
• 稍微改变/改善环境的定义wide

• 采用文档主体来建议解决方案
