Question

3 ,4X - 1,8х+2,3=7,1​

Answer 1

Ответ:

1,6х +2,3=7 ,1

1,6х= 4,8

х=  3

Answer 2

Ответ:

х=3

Пошаговое объяснение:

Сначала нужно перенести неизвестное в левую часть, а известное-в правую. Не забывайте, что при перенесении через "=", знак меняется! То есть:

3,4х-1,8х=7,1 -2,3

1,6х= 4,8

х= 4,8 : 1,6

х= 3

Answer 3

To solve the equation 3(4x - 1) + 8x + 2.3 = 7.1, we can follow these steps:

1. Distribute the 3 to the terms inside the parentheses: 12x - 3 + 8x + 2.3 = 7.1.
2. Combine like terms: 12x + 8x - 3 + 2.3 = 7.1. This simplifies to: 20x - 0.7 = 7.1.
3. Move the constant term to the other side of the equation by adding 0.7 to both sides: 20x = 7.1 + 0.7. This simplifies to: 20x = 7.8.
4. Divide both sides of the equation by 20 to solve for x: x = (7.8) / 20. This simplifies to: x = 0.39.

Therefore, the solution to the equation 3(4x - 1) + 8x + 2.3 = 7.1 is x = 0.39.
