You're welcome.
The equation is asking if "-7 plus 9" is equal to "-9 plus 7." To solve it, you need to perform the mathematical operation on each side of the equation and compare the results.
On the left side of the equation, "-7 plus 9" means you need to add 9 to -7. By doing that, you get 2.
On the right side of the equation, "-9 plus 7" means you need to add 7 to -9. By doing that, you also get 2.
So, both sides of the equation evaluate to the same value, which is 2. Therefore, the equation is true.
The correct answer is A. true.
