.

The correct answer is  |t1 - 74| = 6  degrees.

Valid arguments could be made for either of the answers shown by the other tutors.

If we want to be formal with the formal mathematical language, the "difference between A and B" is always A-B, not B-A. That would mean the equation is, as the one tutor showed, t1-74=6

But very probably the phrase was used informally, so that the temperature t1 could be 6 degrees either side of 74; in that case the equation shown by the other tutor would be correct: abs%28t1-74%29=6
