Answer 3

It seems you've provided a series of equations or expressions. Let's break them down one by one:

1. 51: (-17) This can be interpreted as the equation 51 = -17, which is not true.

2. (-117): 39 Similarly, this can be interpreted as the equation -117 = 39, which is also not true.

3. (-121): (-11) This equation can be rewritten as -121 = -11, which is true.

4. 11: (48-59) This can be simplified as 11 = -11, which is not true.

5. -(61-46): 3 This can be simplified as -15: 3, which is true since -15 divided by 3 equals -5.

6. -(66-31): (-7) This simplifies to -35: -7, which is true since -35 divided by -7 equals 5.

So, out of the given equations, two of them are true: -121 = -11 -15/3 = -5
