SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the given inequality expression
![12<-3x+9<24](https://img.qammunity.org/2023/formulas/mathematics/college/5szj1dtr8aoi8y6uwcrjh73uh64zdwf0aq.png)
STEP 2: Simplify the inequality
![\begin{gathered} -12<-3x+9<24 \\ \mathrm{If}\:a<u><strong>Solving the two inequalities in parts will be:</strong>[tex]\begin{gathered} -12<-3x+9 \\ -12-9<-3x \\ -21<-3x \\ -(21)/(-3)>x \\ 7>x \\ x<7 \end{gathered}]()
For the second part
![\begin{gathered} -3x+9<24 \\ -3x<24-9 \\ -3x<15 \\ x>(15)/(-3) \\ x>-5 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/jrxpt2k699m791iumhpo1b0xnuxtm3zyze.png)
Combine the two results to have:
[tex]\begin{gathered} x<7\quad \mathrm{and}\quad \:x>-5 \\ overlapping\text{ }merging\text{ }intervals \\ -5
Hence, the final solution will be:[tex]-5
