Hey Mahmoud, what you need to do:
1. Alt+click on a stopwatch for x value;
2. Firstly drag pick whip to x’s value;
3. Then add ‘+’ or ‘-‘ (depending whether you want to invert position or keep it the same) and pick whip to Y.
4. Change X position to the original placement you want it to be at.
Now, by changing ‘y’ you will be directly affecting ‘x’. If you want it to be less/more affective, multiply or divide result of ‘x’ position by a number and you are good to go !
