Answer 1

Ответ:

13,36+(−x)=−345.

-х=-345-13,36

-х=-358,36

х=358,36

Answer 2

To find the value of x in the equation 13 + 36 + (-x) = -345, we can follow these steps:

Step 1: Combine like terms on the left side of the equation. Step 2: Isolate x on one side of the equation. Step 3: Solve for x.

Step 1: 13 + 36 - x = -345

Step 2: To isolate x, we need to get rid of the constants on the left side. Let's move 13 and 36 to the right side by subtracting them from both sides of the equation:

-x = -345 - 13 - 36 -x = -394

Step 3: To solve for x, we need to get rid of the negative sign in front of x. To do that, we can multiply both sides of the equation by -1:

x = 394

So, the value of x is 394 (as a decimal fraction, it is simply 394).
