Align both text objects right. Open Visual logic.
Grab these Objects from the left side under "Scene Objects":
Right Text Object - x.position
Right Text Object - bounding.box.width
Left Text Object - x.position
Grab an "Add" function block from the right side under 'math'
Put Both Right Text Objects into the left side of the "Add" function block.
Pull the result into the Left Text Objects x.position
This should get your desired result, but will also depend on if your objects are grouped and what their x.position is. If it is negative, you might want to try replacing the add with a subtract and play around with which number your putting into the add block first. If this doesn't give you the result you want. try multiplying by -1.
ps. if you are trying to center everything horizontally. I would just make your left text justified right and your right text justified left then stick the two near each other.
