these can be treated as a regular equation, but you must keep the greater than (>) or the less than (<) signs in the initial order

- 4x - 9 > 7

*(- 4x - 9) + 9 > (7) + 9*

**comment:**intermediate equation―adding + 9 to both sides of the inequality does not change it- 4x > 16

*(- 4x) / -4 > (16) / -4*

**comment:**intermediate equation―dividing both sides of the inequality by -4 does not change itthe final answer is:

x > -4
