Let A, B, and C represent the 3 sides of the triangle.
A = 22
B = 2x - 2
C = x
Note: This problem is not asking you to solve for x. It is asking for an inequality that defines the possible lengths of the second and third sides.
Here is the set up:
B + A > C becomes
(2x - 2) + 22 > x
You finish.

I am not sure that the setup of the other tutor is correct.
In any case, from that setup NOTHING follows.
O, sorry !!
Still something follows. Namely, from
(2x - 2) + 22 > x
follows
X > - 20.
