How do I do this question:

-6|7-x|< -30

So far I have that x=2, but I know that it's more than just 2. How do I denote/find that?

first of all isolate the absolute value expression by dividing by -6, remembering that we have to reverse the inequality sign if we divide or multiply by a negative.

|7-x| > 5

then 7-x > 5 OR -7 + x > 5

-x > -2 OR x > 12

x < 2 OR x > 12
