Solve a given equation and return the value of 'x' in the form of a string "x=#value". The equation contains only '+', '-' operation, the variable 'x' and its coefficient. You should return "No solution" if there is no solution for the equation, or "Infinite solutions" if there are infinite solutions for the equation.
If there is exactly one solution for the equation, we ensure that the value of 'x' is an integer.
\n
Example 1:
\n\n\nInput: equation = "x+5-3+x=6+x-2"\nOutput: "x=2"\n\n\n
Example 2:
\n\n\nInput: equation = "x=x"\nOutput: "Infinite solutions"\n\n\n
Example 3:
\n\n\nInput: equation = "2x=x"\nOutput: "x=0"\n\n\n
\n
Constraints:
\n\n3 <= equation.length <= 1000equation has exactly one '='.equation consists of integers with an absolute value in the range [0, 100] without any leading zeros, and the variable 'x'.求解一个给定的方程，将x以字符串 \"x=#value\" 的形式返回。该方程仅包含 '+' ， '-' 操作，变量 x 和其对应系数。
如果方程没有解或存在的解不为整数，请返回 \"No solution\" 。如果方程有无限解，则返回 “Infinite solutions” 。
题目保证，如果方程中只有一个解，则 'x' 的值是一个整数。

示例 1：
\n\n\n输入: equation = \"x+5-3+x=6+x-2\"\n输出: \"x=2\"\n\n\n
示例 2:
\n\n\n输入: equation = \"x=x\"\n输出: \"Infinite solutions\"\n\n\n
示例 3:
\n\n\n输入: equation = \"2x=x\"\n输出: \"x=0\"\n\n\n

提示:
\n\n3 <= equation.length <= 1000equation 只有一个 '='. [0, 100] 范围内且无任何前导零的整数和变量 'x' 组成。\\u7248\\u672c\\uff1a \\u7f16\\u8bd1\\u65f6\\uff0c\\u5c06\\u4f1a\\u91c7\\u7528
