Question

Babanın 76 yaşı var. Nəvələri 5 və 7 yaşındadırlar. Neçə ildən sonra babanın yaşı Nəvələrin yaşları cəmindən 3 dəfə çox olar? ​

Answer 1

Ответ:  через  8 років .

Пошаговое объяснение:

Нехай через  х років дідо буде в 3 рази старший .

       Рівняння :    76 + х = 3*( 5 + х + 7 + х ) ;

                            76 + х = 3*( 12 + 2х ) ;

                            76 + х = 36 + 6х ;

                             6х - х = 76 - 36 ;

                                   5х = 40 ;

                                      х = 8 .

Answer 2

Ответ:

(76+х)/(5+7+2х)=3

76+х=3*(5+7+2х)

76+х=3*(12+2х)

6х-х=76-36

5х=40

х=40/5=8 лет

Answer 3

Calculating the Age Difference:

To find out how many years it will take for the father's age to be three times the combined age of his grandchildren, we can set up an equation.

Let's denote the father's age as F, and the ages of his grandchildren as G1 and G2.

Given: - F = 76 - G1 = 5 - G2 = 7

We want to find the number of years, denoted as x, after which the father's age will be three times the combined age of his grandchildren.

The equation can be set up as: F + x = 3 * (G1 + G2)

Solving for x:

Substitute the given values into the equation: 76 + x = 3 * (5 + 7)

Simplify the equation: 76 + x = 3 * 12 76 + x = 36

Now, solve for x: x = 36 - 76 x = -40

The negative result indicates that the father's age will never be three times the combined age of his grandchildren, given the current ages and the father's age.

Therefore, based on the current ages provided, the father's age will never be three times the combined age of his grandchildren.
