Two sides of a triangle measure 2x – 4 and 7x – 2 units, respectively. Which of these is a possible length for the third side of the triangle?

You don't list any "which of these ..."

However, the sum of any two sides must be greater than 3rd side ,
so ..
2x-4 + 7x-2
= 9x - 6

So whichever is less than 9x-6 could be a
third side
