Question

19,6+y=7(1,2-y)ОТВЕТ?​

Answer 1

Ответ:

-1,4

Пошаговое объяснение:

19,6+y=7(1,2-y)

19,6+у=8,4-7у

Перенесем у влево, а обычные числа вправо.

Получим у+7у=8,4-19,6

8у= -11,2

у= -11,2:8

у= -1,4

Answer 2

Ответ:

19,6+у=8,4-7у

у+7у=8,4-19,6

8у=-11,2

у=-11,2 :8

у=-1,4

19,6+(-1,4)=7(1,2-(-1,4)

18,2=7*2,6

18,2=18,2

Answer 3

To solve the equation 19.6 + y = 7(1.2 - y), we can follow these steps:

1. Distribute the 7 on the right side of the equation: 19.6 + y = 7 * 1.2 - 7 * y

2. Simplify the right side: 19.6 + y = 8.4 - 7y

3. Move all terms containing y to one side of the equation: y + 7y = 8.4 - 19.6

4. Combine like terms: 8y = -11.2

5. Divide both sides by 8: y = -11.2 / 8

6. Calculate the value: y = -1.4

So, the solution to the equation 19.6 + y = 7(1.2 - y) is y = -1.4.
