For part a I would say you can’t use that translation to change it back to the original triangle. I tried the rule out for myself
My coordinate was 3, 6 and applied the -7 -6 rule and got -4,0.
Then I used the rule that they have to translate it back which was -6 -7 and there’s no way it can be translated back to 3, 6
So the answer is no the rule can’t be used to translate it back
