Answer
$ x-7 \lt -2\;\;$ or $\quad x-7\gt 2.$
Work Step by Step
Solving an Absolute VaIue Inequality:
If $ u $ is an algebraic expression and $ c $ is a positive number, then:
1) The solutions of $|u| \lt c $ are the numbers that satisfy $-c \lt u \lt c.$
2) The solutions of $|u|\gt c $ are the numbers that satisfy $ u\lt -c $ or $ u\gt c.$
These rules are valid if $ \lt$ is replaced by $\leq $ and $ \gt \mathrm{i}\mathrm{s}$ replaced by $\geq.$

Apply case 2,
$ x-7 \lt -2\;\;$ or $\quad x-7\gt 2.$
