Question

8,25+(−x)=−2 4/5 рншить Уравнение ппжжжжжж​

Answer 1

Ответ:

х = 11,5

Пошаговое объяснение:

8,25 - x = - 2,8 (переводим 2 4/5 в десятичную дробь)

-x = -2,8 - 8,25 (c иксами влево без иксов вправо )

-х = -11,05 \* (-1) (домножаем на -1 , чтобы избавиться от отрицательного икса)

Answer 2

To solve the equation 8.25 + (-x) = -2 4/5, we can follow these steps:

Step 1: Convert the mixed number -2 4/5 into a decimal. To do that, we subtract the fraction from the whole number:

-2 - 4/5 = -2 - 0.8 = -2.8

So, the equation becomes:

8.25 + (-x) = -2.8

Step 2: Simplify the equation by adding x to both sides to isolate the variable:

8.25 + (-x) + x = -2.8 + x

Simplifying further:

8.25 = -2.8 + x

Step 3: Subtract -2.8 from both sides:

8.25 - (-2.8) = -2.8 - (-2.8) + x

Simplifying:

8.25 + 2.8 = x

Step 4: Add 8.25 and 2.8:

11.05 = x

Therefore, the solution to the equation 8.25 + (-x) = -2 4/5 is x = 11.05.
