For this problem we have the following expression given:
![\left\lbrack (12-5)-12\right\rbrack =6](https://img.qammunity.org/2023/formulas/mathematics/college/fj71afcb5cy5d8y7a2dnjbmk2squ74fr26.png)
We assume that the question is verify if the equation is correct so first we solve the numbers in the parenthesis:
![\left\lbrack 7-12\rbrack=-5\right?](https://img.qammunity.org/2023/formulas/mathematics/college/vez26bku9o2qerr8gct9ja8y8kvwgjsuf1.png)
And then the final answer for this case would be -5 and not 6 so then the statement for this case is False.
