Question

14-7 21/29+ х + 4 целых 23/29 = 12 целых 2/29

Answer 1

Ответ: х = 1

Пошаговое объяснение:

14 - 7 цел. 21/29 + х + 4 цел. 23/29 = 12 цел.2/29

6 цел. 8/29 + х + 4 цел. 23 /29 = 12 цел.2/29

11 цел. 2/29 + х = 12 цел. 2/29

х = 12 цел. 2/29 - 11 цел. 2/29

х = 1

Проверка:  14 - 7 цел. 21/29 + 1 + 4 цел. 23/29 = 12 цел.2/29

                     6 цел. 8/29 + 1 + 4 цел. 23 /29 = 12 цел.2/29

                     11 цел. 2/29 + 1 = 12 цел.2/29

Answer 2

To solve the equation, let's break it down step by step.

First, let's simplify the left side of the equation: 14 - 7 = 7 21/29 + х + 4 целых 23/29

Next, let's add the mixed numbers: 4 целых 23/29 = (4 * 29 + 23) / 29 = 119/29

Now, the equation becomes: 7 + 21/29 + х + 119/29 = 12 целых 2/29

To combine the terms on the left side, we need a common denominator, which in this case is 29.

Rewriting the equation with the common denominator: (7 * 29 + 21 + 29х + 119) / 29 = (12 * 29 + 2) / 29

Simplifying the equation further: (203 + 21 + 29х + 119) / 29 = (348 + 2) / 29

Combining like terms: (343 + 29х) / 29 = 350 / 29

Now, let's eliminate the denominator by multiplying both sides of the equation by 29: 29 * (343 + 29х) / 29 = (350 / 29) * 29

Simplifying: 343 + 29х = 350

Subtracting 343 from both sides: 29х = 350 - 343 29х = 7

Dividing both sides by 29: х = 7/29

Therefore, the solution to the equation is х = 7/29.
