Question

Решите уравнение (86*4-c)+356=143*4 срочно!!

Answer 1

Ответ:

с=128

Пошаговое объяснение:

(86*4-c)+356=143*4

(86*4-c)+356=572

86*4-c= 572-356

86*4-c=216                     86*4=344

344-с=216

с=344-216

с=128

Answer 2

Ответ:

c = 128

Пошаговое объяснение:

$(86*4-c)+356=143*4$

$(86*4-c)+356=572$

$(86*4-c)=216$

$(344-c)=216$

$c=344-216$

$c=128$

Answer 3

To solve the equation (86 * 4 - c) + 356 = 143 * 4 + c, we can follow these steps:

1. Simplify both sides of the equation by performing the operations within the parentheses and combining like terms: - On the left side, we have (86 * 4 - c) + 356 = 344 - c + 356 = 700 - c. - On the right side, we have 143 * 4 + c = 572 + c.

2. Now we have the equation 700 - c = 572 + c.

3. To isolate the variable c, we can add c to both sides of the equation: - 700 - c + c = 572 + c + c. - Simplifying further, we get 700 = 572 + 2c.

4. Next, we can subtract 572 from both sides of the equation: - 700 - 572 = 572 + 2c - 572. - Simplifying further, we get 128 = 2c.

5. Finally, we can solve for c by dividing both sides of the equation by 2: - 128 / 2 = 2c / 2. - Simplifying further, we get 64 = c.

Therefore, the solution to the equation (86 * 4 - c) + 356 = 143 * 4 + c is c = 64.
