We are given the following compound inequality and want to find the values of x that makes this true:
![3](/tpl/images/0567/1767/89df2.png)
Add 3 to all parts of the inequality
![3\boxed{+3}](/tpl/images/0567/1767/b7a84.png)
![6](/tpl/images/0567/1767/17c84.png)
Divide all parts of the inequality by 2
![6\boxed{\div 2}](/tpl/images/0567/1767/236d8.png)
![3](/tpl/images/0567/1767/52799.png)
Converting this into interval notation gives us:
![x:(3,7.5)](/tpl/images/0567/1767/42ef3.png)
Let me know if you need any clarifications, thanks!
