Question

1) 0,6 – 1,6 ( х-4) = 3 ( 7- 0,4х);

Answer 1

Ответ:

Пошаговое объяснение:

0,6 – 1,6 ( х-4) = 3 ( 7- 0,4х);

0,6 - 1,6x + 6,4 = 21 - 1,2x

7 - 1,6x = 21 - 1,2x

1,6x - 1,2x = 7 - 21

0,4x = -14

x = -14 : 0,4

x = -35

Answer 2

Ответ:

х = -35

Пошаговое объяснение:

0,6 – 1,6 ( х-4) = 3 ( 7- 0,4х)

0,6 - 1,6х + 6,4 = 21 - 1,2х

-1,6х + 1,2х = 21 - 0,6 - 6,4

-0,4х = 14

х = 14 : (-0,4)

х = -35

Проверим:

0,6 - 1,6(-35 - 4) = 3((7 - 0,4*(-35))

0,6 -1,6*(-39) = 3(7 + 14)

0,6 + 62,4 = 3 * 21

63 = 63

Answer 3

It seems like you've provided an equation that needs to be solved for the variable "x." Let's work through the steps to solve it:

The equation you've given is: 0.6 - 1.6(x - 4) = 3(7 - 0.4x)

Let's solve it step by step:

Step 1: Distribute the constants and variables within the parentheses: 0.6 - 1.6x + 6.4 = 21 - 1.2x

Step 2: Combine like terms on both sides of the equation: 6.4 - 1.6x = 21 - 1.2x

Step 3: Move all terms involving "x" to one side of the equation and the constants to the other side: -1.6x + 1.2x = 21 - 6.4

Simplify: -0.4x = 14.6

Step 4: Solve for "x" by dividing both sides by -0.4: x = 14.6 / -0.4 x = -36.5

So, the solution for the equation is x = -36.5.
