Answer 1

Ответ:

Пошаговое объяснение:

1) -х=57

Х=-57

2)-(-х)=-0,4

Х=-0,4

Answer 2

1) -x=57

x= -57

2) -(-x)= -0,4

x= -0,4

Answer 3

1. To find the value of x when -x = 57, we can solve for x:

-x = 57

To get x alone on one side of the equation, we can multiply both sides by -1 (since multiplying by -1 on both sides of an equation will not change its solution):

-1 * -x = -1 * 57

This simplifies to:

x = -57

So the value of x is -57.

2. To find the value of x when -(-x) = -0.4, we can simplify the equation first:

-(-x) = -0.4

The double negative cancels out, leaving us with:

x = -0.4

So the value of x is -0.4.
