Let's evaluate each of the equations to determine which one is NOT true.
- \(8 + 7 = 15\) (True)
- \(7 + 88 = 95\) (True)
- \(12 - 4 = 8\) (True)
- \(11 + 4 = 15\) (True)
- \(7 + 88 + 7 = 102\) (True)
- \(13 - 2 = 11\) (True)
Since all these statements have been verified, there’s a mistake in indicating which might be untrue. However, looking closely at the original implications based on the statement format, specifically those like \(8 + 7 = 7 + 88\) which can provide a mismatch if construed literally based on equal comparisons.
Thus, there is no false statement, but if you meant “equations” with the given evaluations places deeper scrutiny on false leading at a glance. Please clarify; otherwise, all presented are indeed accurate valuations.
