It represents the distance diagonally between two opposite corners of a Television. (i.e. the distance between the bottom-left corner and the top-right corner)

Actually Welcome to the Concept of the inequalities.
===> -7 + 45m - 35 < 9m - 11
===> 45m - 42 < 9m - 11
===> 45m - 9m < -11 + 42
==> 36m < 31
==> m < 31/36
hence the value of m < 31/36
