Question

7,88+× = 12,42 (×+17,3)-10,84=9,56​

Answer 1

7,88 + x = 12,42

x = 12,42 - 7,88

x = 4,54

(x + 17,3) - 10,84 = 9,56

x + 17,3 - 10,84 = 9,56

x = 9,56 - 17,3 + 10,84

x = 3,1

Answer 2

Ответ:

1. 7,88+× = 12,42           х = 4,54
2. (×+17,3)-10,84=9,56​         х = 3,1

Пошаговое объяснение:

1. 12,42 - 7,88 = 4,54

        x = 12,42 - 7,88

        х = 4,54

     2.(х + 17,3)-10,84=9,56

        (х + 17,3)=9,56+10,84

        (х + 17,3)=20,4

        х = 20,4 - 17,3

        х = 3,1

Если мы переносим число с одной стороны уравнения на другую, то знак числа всегда меняется (если положительное число, то при переносе становится отрицательным. Если же число отрицательное, то при переносе оно становится положительным).

Answer 3

To solve the equation 7.88 + x = 12.42(x + 17.3) - 10.84 = 9.56, you can follow these steps:

1. Distribute the 12.42 on the right side of the equation: 7.88 + x = 12.42x + 12.42 * 17.3 - 10.84 = 12.42x + 213.846 - 10.84 = 12.42x + 202.006

2. Combine like terms on the right side of the equation: 7.88 + x = 12.42x + 202.006 - 10.84

3. Subtract 202.006 and 10.84 from both sides of the equation to isolate x: 7.88 - 202.006 - 10.84 + x = 12.42x - 202.006 - 10.84 - 202.006

4. Simplify the equation: x - 204.966 = 12.42x - 415.846

5. Move the 12.42x term to the left side of the equation by subtracting 12.42x from both sides: x - 12.42x - 204.966 = -415.846

6. Combine like terms on both sides: -11.42x - 204.966 = -415.846

7. Add 204.966 to both sides to isolate the x term: -11.42x - 204.966 + 204.966 = -415.846 + 204.966

8. Simplify the equation further: -11.42x = -210.88

9. Finally, divide both sides by -11.42 to solve for x: x = -210.88 / -11.42 x ≈ 18.49

So, the solution to the equation is approximately x ≈ 18.49.
