If 25 + d = 36, does 25 + d – 25 = 36 – 20? Explain.

No.

From 25 + d = 36, subtracting 25 from both sides gives d = 36 − 25 = 11. So 25 + d − 25 = d = 11, but 36 − 20 = 16. Since 11 ≠ 16, the given equality is false.

You must perform the same operation to both sides of an equation to preserve equality; subtracting 25 from the left and 20 from the right does not.
