# How do you solve the inequality #9 > -3 (x - 1) ≥ -12#?

##### 1 Answer

#### Explanation:

Given:

Divide throughout by 3 (does not change the signs)

Subtract 1 throughout

Swap sides and change the negatives to positives. Keep the inequality the same way round.

Same thing as: add 5 to both sides and add

Same thing as: multiply both sides by (-1) and turn the inequality sign the other way round.

Swap sides and change the signs but keep the inequality the same way round.
