Martin is 6 years younger than his sister. the sum of their ages is no more than 22 years. enter an inequality that can be used to represent this situation in the box, where x represents martin's sister's age. $< $≤≥$\ngtr$≯$\nless$≮

Just took the test and the answer was: x + x - 6 ≤ 22. I thought it was x < 14 but it wasn't. This was the only problem I got wrong.
