Which property of equality could be used to solve x - (-6) = 18?

The property of equality that can be used to solve x - (-6) = 8 is the addition property of equality.

Step-by-step explanation:

When subtracting a negative in an equality problem, you would have to use the reverse operation which would be the addition property of equality. Subtracting a negative may seem like adding a positive but when it comes to equality property problems, you still use the opposite operation.

x - (-6) = 18

   +-6     +-6

x = 12.

12 - (-6) = 18.
