Answer 2

Let's solve the given equations step by step:

1. -x = 1999

To isolate x, we can multiply both sides of the equation by -1: (-1)(-x) = (-1)(1999) x = -1999

So the solution for the first equation is x = -1999.

2. -(-x) = -6

The double negative can be simplified to a positive: x = -6

So the solution for the second equation is x = -6.

Therefore, the system of equations has two different solutions: x = -1999 and x = -6.
