Question

4(2x+1)=2.7-7(1.3-0.4х)

Answer 1

Відповідь:

x = -2

Покрокове пояснення:

4(2x+1)=2.7-7(1.3-0.4х)

8x + 4 = 2,7 - 9,1 + 2,8x

8x - 2,8x  = 2,7 - 9,1 - 4

5,2x = -10,4

x = -10,4 : 5,2

x = -2

Answer 2

Ответ:

х=-2

Пошаговое объяснение:

1. открываем скобки

8х+4=2.7-9.1+2.8х

2. неизвестное влево, известное вправо, меняем знаки по переносу

8х-2.8х=2.7-9.1-4

3. решаем

5.2х=-10.4

х=10.4÷5.2

х=-2

Answer 3

To solve the equation $4(2x+1) = 2.7 - 7(1.3 - 0.4x)$, we'll start by distributing and simplifying on both sides:

First, distribute on the left side: $8x + 4 = 2.7 - 7(1.3 - 0.4x)$

Next, distribute on the right side: $8x + 4 = 2.7 - 9.1 + 2.8x$

Combine like terms on the right side: $8x + 4 = -6.4 + 2.8x$

Now, let's isolate $x$ on one side of the equation. Subtract $2.8x$ from both sides and subtract 4 from both sides: $8x - 2.8x = -6.4 - 4$

Combine like terms on both sides: $5.2x = -10.4$

Finally, divide by 5.2 to solve for $x$: $x = \frac{-10.4}{5.2}$

$x = -2$

Therefore, the solution to the equation is $x = -2$.
