Question

Уравнения: (х-405)+300=405

Answer 1

(Х - 405) + 300 = 405

Х - 405 = 405 - 300

Х - 405 =105

Х = 405 + 105

Х =510

Проверка : ( 510- 405) + 300 = 406

Ответ : 510

Answer 2

To solve the equation (x - 405) + 300 = 405, follow these steps:

Step 1: Combine like terms on the left side of the equation.

(x - 405) + 300 = 405 x - 105 = 405

Step 2: Isolate the variable term (x) by moving the constant term (-105) to the other side of the equation by adding 105 to both sides.

x - 105 + 105 = 405 + 105 x = 510

Step 3: Check the solution by substituting the value of x back into the original equation.

(x - 405) + 300 = 405 (510 - 405) + 300 = 405 105 + 300 = 405 405 = 405

The equation is true when x = 510, so the solution is x = 510.
