Question

пусть у нас есть два числа, сумма которых равна 0. если мы добавим 123 к одному из них, получим значение, которое вдвое больше другого числа. что за числа?​

Answer 1

Ответ:

41 и -41

Пошаговое объяснение:

ПУсть первое число Х, тогда второе Y

X+Y = 0

X +123 = 2 Y

X = - Y

-Y +123 =2Y

123 = 3 Y

Y = 41 - второе

X = -41 первое.

Проверяем -41+123 = 82 ( 2Y) - верно

Answer 2

Problem Analysis

We are given two numbers whose sum is equal to 0. If we add 123 to one of the numbers, the result will be twice the value of the other number. We need to find the values of these two numbers.

Solution

Let's assume the two numbers are x and y. According to the given information, we have the following equations:

1. x + y = 0 (The sum of the two numbers is 0) 2. x + 123 = 2y (If we add 123 to one of the numbers, the result is twice the value of the other number)

To solve this system of equations, we can substitute the value of x from the first equation into the second equation:

0 + 123 = 2y

Simplifying the equation, we get:

123 = 2y

Dividing both sides of the equation by 2, we find:

y = 61.5

Now, we can substitute the value of y back into the first equation to find the value of x:

x + 61.5 = 0

Simplifying the equation, we get:

x = -61.5

Therefore, the two numbers are -61.5 and 61.5.

Answer

The two numbers are -61.5 and 61.5.
