Question

25 - 4(x + 1,8) = 9,8​

Answer 1

Ответ:

2

Пошаговое объяснение:

25 - 4х - 7,2 = 9,8

-4х = 9,8 - 25 + 7,2

-4х = -8

х = 8 : 4

х = 2

Answer 2

To solve the equation 25 - 4(x + 1.8) = 9.8, we can follow these steps:

1. Distribute the 4 to the terms inside the parentheses: 25 - 4x - 4(1.8) = 9.8

2. Simplify the expression inside the parentheses: 25 - 4x - 7.2 = 9.8

3. Combine like terms: -4x + 17.8 = 9.8

4. Move the constant term to the other side of the equation: -4x = 9.8 - 17.8

5. Simplify the right side: -4x = -8

6. Divide both sides of the equation by -4 to solve for x: x = -8 / -4

7. Simplify the right side: x = 2

Therefore, the solution to the equation 25 - 4(x + 1.8) = 9.8 is x = 2.
