Question

-2,9+(-х)=-3,8 в ответе 0,9

Answer 1

-2,9 + (-x) = -3,8

-x = -3,8 + 2,9

-x = -0,9

x = 0,9

Answer 2

Let's solve the given equation step by step:

-2.9 + (-x) = -3.8

First, let's combine the numbers on the left side:

-2.9 - x = -3.8

Next, we want to isolate the variable x on one side of the equation. To do that, we'll move the constant term (-2.9) to the right side by adding it to both sides of the equation:

• x = -3.8 + 2.9

Now, let's calculate the result:

• x = -0.9

To solve for x, we need to get x alone on the left side of the equation. Since there is a negative sign in front of x, we can multiply both sides by -1 to cancel it out:

x = 0.9

So, the value of x that satisfies the equation is x = 0.9, which matches the answer you provided.
