Question

1) Q: A: If 5 + x = 12, and you add -5 to the left side of equation, what should you add to right side of equation

Answer 1

You can "add" like you say or you could just call it subtracting. If you subtract 5 from 5 you still get zero.  Then on the right side, you would do the same. You would subtract 5 from 12 getting x, which is 7.If you added you would still get the same answers but it is easier to say just subtract. Anything you do to the left, do to the right.
