Question

Сумма двух чисел равна 126,причем одно число меньше другого на 18. найди эти числа

Answer 1

Пусть x - меньшее число, тогда x+18 - большее число

Составим уравнение:

x+x+18=126

2x+18=126

2x=126-18

2x=108

x=54 - меньшее число

54+18=72 - большее число

Ответ: 54 и 72

Answer 2

Ответ:

Пошаговое объяснение:

126/2+18/2=72

126/2-18/2=54

Answer 3

Let's denote the two numbers as x and y. We are given two pieces of information:

1. The sum of the two numbers is 126: x + y = 126.
2. One number is 18 less than the other: x = y - 18.

Now, we can use these two pieces of information to find the values of x and y.

Substitute the value of x from the second equation into the first equation:

(y - 18) + y = 126

Now, combine like terms:

2y - 18 = 126

Add 18 to both sides of the equation to isolate 2y:

2y = 126 + 18 2y = 144

Now, divide both sides by 2 to find the value of y:

y = 144 / 2 y = 72

Now that we have the value of y, we can find the value of x using the second equation:

x = y - 18 x = 72 - 18 x = 54

So, the two numbers are 54 and 72.
