Given a string equation representing a linear equation, solve the equation and return the value of x as a string.

The result should be formatted as follows:

• If the equation has a single unique solution, return "x=#", where # represents the integer value of x.

• If the equation has infinitely many solutions, return "Infinite solutions".

• If the equation has no solution, return "No solution".

Constraints:

• $3 \leq$ equation.length $\leq 1000$

• equation has exactly one '='.

• equation consists of integers with an absolute value in the range $[0, 100]$ without any leading zeros, and the variable 'x'.

• The input is generated such that if there is a single solution, it will be an integer.
