Question

0.8(2х-1)=-2,4(3х+4)​

Answer 1

Пошаговое объяснение:

0,8(2х - 1) = -2,4(3х + 4)

1,6х - 0,8 = -7,2х - 9,6

1,6х + 7,2х = -9,6 + 0,8

8,8х = -8,8

х = -8,8 : 8,8

х = -1

Answer 2

Відповідь:

Покрокове пояснення:

0.8(2х-1)=-2,4(3х+4)

1,6x-0,8=-7,2x-9,6

1,6х+7,2х=-9,6+0,8

8,8х=-8,8

х=-1

Answer 3

To solve the given equation, we'll first distribute the coefficients and variables, then isolate $x$.

Given equation: $0.8(2x - 1) = -2.4(3x + 4)$

Now, distribute the coefficients: $1.6x - 0.8 = -7.2x - 9.6$

Next, let's gather the $x$ terms on one side and the constant terms on the other side: $1.6x + 7.2x = -0.8 - 9.6$

Combine the $x$ terms and constants: $8.8x = -10.4$

Now, isolate $x$ by dividing both sides by $8.8$: $x = \frac{-10.4}{8.8}$

Now, calculate $x$: $x \approx -1.1818$
