Open the parenthesis
![9 / 3[12- 22]](https://img.qammunity.org/2020/formulas/mathematics/middle-school/laawjfzphvtdwiv5xm4zvbeovyldatguv6.png)
![9 / 3[-10]](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xi9mw9g9b35gf7imoo72p76ux84q1npdq9.png)
Hence, the value of the expression is -0.3
