Given the equation:
![-(-2+11)=2+(-11)](https://img.qammunity.org/2023/formulas/mathematics/high-school/vlceincm0frsoj038aspr4kua06irqzm2a.png)
Let's identify the property demonstrated in the given equation.
The property demonstrated here is the distributive property.
To simplify the left side, we are to distribute the - sign to the terns in the parentheses using distributive property.
We have:
![\begin{gathered} -(-2)+(-11) \\ \\ =2+(-11) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/5eayrqsx7rebkkx343aghldnbci64rbis9.png)
Therefore, the property demonstrated here is the distributive property.
ANSWER:
Distributive property.
