Question

2800-(х-357)=100 ришите уравнение пжж

Answer 1

$2800 - (x - 357) = 100 \\ 2800 - x + 357 = 100 \\ 3157 - x = 100 \\ - x = 100 - 3157 \\ - x = - 3057 \\ x = 3057$

Ответ: х = 3057

Answer 2

2800-(х-357)=100

2800-х+357=100

3157-х=100

-х=100-3157

-х= -3057

х=3057

_______________

2800-(3057-357)=100

100=100

Answer 3

To solve the equation, follow these steps:

1. Distribute the negative sign to the terms inside the parentheses: 2800 - x + 357 = 100

2. Combine like terms: 2800 + 357 - x = 100

3. Simplify the left side of the equation: 3157 - x = 100

4. To isolate the variable "x," subtract 3157 from both sides of the equation: -x = 100 - 3157

5. Simplify the right side: -x = -3057

6. To solve for "x," multiply both sides by -1 (to get rid of the negative sign in front of "x"): x = 3057

So the solution to the equation is: x = 3057
