Answer 2

Ответ:

Пошаговое объяснение:

46,06 - 9,8х + 6 + 1,2х = 13

-9,8х + 1,2х = 13 - 46,06 - 6

-8,6х = -39,06

х = -39,06 : (-8,6)

х = -39. 6/100 : (-8. 6/10)

х = -39. 3/50 : (-8. 3/5)

х = -1953/50 : (-43/5)

х = -1953/50 * (-5/43)

х = -1953/10 * (-1/43)

х = 1953/430

х = 4. 233/430

Answer 3

To solve the equation $9.8(4.7 - x) + 1.2(5 + x) = 13$, follow these steps:

1. Distribute the numbers inside the parentheses: $9.8 * 4.7 - 9.8 * x + 1.2 * 5 + 1.2 * x = 13$

2. Multiply the numbers: $45.66 - 9.8x + 6 + 1.2x = 13$

3. Combine like terms: $-9.8x + 1.2x + 45.66 + 6 = 13$

4. Combine the $x$ terms: $-8.6x + 51.66 = 13$

5. Subtract 51.66 from both sides of the equation to isolate the $x$ term: $-8.6x = 13 - 51.66$

6. Simplify the right side: $-8.6x = -38.66$

7. Now, divide both sides by -8.6 to solve for $x$: $x = \frac{-38.66}{-8.6}$

8. Calculate the value of $x$: $x \approx 4.5$

So, the solution to the equation is $x \approx 4.5$.
