-x=-(-18)

x= -18

Answer 2

It appears you have two equations:

1. -x = 20
2. -x = -(-18)

Let's solve them one by one:

1. For the first equation, -x = 20, you can isolate x by multiplying both sides of the equation by -1 to get:

   -x * (-1) = 20 * (-1)

   This simplifies to:

   x = -20

So, the solution to the first equation is x = -20.

2. For the second equation, -x = -(-18), you can simplify it by removing the double negation:

   -x = 18

Now, you can isolate x by multiplying both sides of the equation by -1:

-x * (-1) = 18 * (-1)

This simplifies to:

x = -18

So, the solution to the second equation is x = -18.

Therefore, the solutions to the given equations are:

1. x = -20
2. x = -18
