Question

6.18.000+300+х=20.000 75 900—у=45.000+5.000

Answer 1

Пошаговое объяснение:

1) 18000 + х + 300 = 20000;

х = 20000 - 18000 - 300;

х = 1700;

Ответ: 1700.

2) 900000 - 800 - х = 100000;

В первую очередь переносим числа с левой части в правую, поменяв знаки на противоположные.

-х = 100 000 - 900 000 + 800;

-х = -799200;

х = 799200;

Ответ: 799200.

3) 75900 - у = 45000 + 5000;

Первым действием находим значение суммы в правой части уравнения.

75900 - у = 50000;

Для нахождения вычитаемого "у" мы от уменьшаемого 75900 вычитаем разность 50 000.

у = 75900 - 50000;

у = 25900;

Ответ: 25900

Answer 2

To solve the equations, let's simplify them step by step:

Equation 1: 6.18.000 + 300 + х = 20.000

I assume there might be an error in the equation you provided. It seems you wrote "6.18.000," which could be a typo. If you meant 618,000, then the equation can be simplified as follows:

618,000 + 300 + х = 20,000

Combine the numbers on the left side:

618,300 + х = 20,000

Subtract 618,300 from both sides:

х = 20,000 - 618,300

х = -598,300

So the solution for the first equation is х = -598,300.

Equation 2: 75,900 - у = 45,000 + 5,000

Combine the numbers on the right side:

75,900 - у = 50,000

Add у to both sides:

75,900 = 50,000 + у

Subtract 50,000 from both sides:

75,900 - 50,000 = у

25,900 = у

So the solution for the second equation is у = 25,900.

Therefore, the solutions for the given equations are: х = -598,300 and у = 25,900.
