Please solve the programming task below using a self-contained code snippet in a markdown code block.

Given four integers sx, sy, tx, and ty, return true if it is possible to convert the point (sx, sy) to the point (tx, ty) through some operations, or false otherwise.
The allowed operation on some point (x, y) is to convert it to either (x, x + y) or (x + y, y).
 
Please complete the following python code precisely:
```python
class Solution:
    def reachingPoints(self, sx: int, sy: int, tx: int, ty: int) -> bool:
```
