Answer 1

Ответ: 190

Пошаговое объяснение:

(644 - х) + 277 = 731

644 - х + 277 = 731

-х = 731-644-277

-х = -190

х = 190

Answer 2

Ответ:

644-x=731-277

644-x=454

x=644-454

x=190

Answer 3

To solve for the variable "x" in the equation (644 - x) + 277 = 731, you can follow these steps:

1. Start by simplifying the equation: (644 - x) + 277 = 731

2. Combine like terms on the left side of the equation: 644 - x + 277 = 731

3. Combine the constants on the left side: 644 + 277 - x = 731

4. Add 644 and 277 to get a new constant on the left side: 921 - x = 731

5. Now, isolate the variable "x" by moving the constant term to the right side of the equation. To do this, subtract 921 from both sides of the equation: -x = 731 - 921

6. Simplify the right side: -x = -190

7. Finally, solve for "x" by multiplying both sides of the equation by -1 to isolate "x": x = 190

So, the solution to the equation (644 - x) + 277 = 731 is x = 190.
