Question

0,3(8-3х)=3,2-0,8(х-7)​

Answer 1

Ответ:

x = -64

Пошаговое объяснение:

0,3(8 - 3х) = 3,2 - 0,8(х - 7)​

2,4 - 0,9x = 3,2 - 0,8x + 5,6

2,4 - 0,9x = 8,8 - 0,8x

-0,9x + 0,8x = 8,8 - 2,4

-0,1x = 6,4

x = 6,4/(-0,1)

x = -64

Answer 2

Ответ:

Пошаговое объяснение:

0,3(8-0,3x)=3,2-0,8(x-7)

2,4-0,09x=3,2-0,8x-5,6

-0,09x+0,8x=3,2-5,6-2,4

0,71x=-4,8

x=-4,8/0,71

x=-6,76

Answer 3

To solve the equation 0.3(8 - 3x) = 3.2 - 0.8(x - 7), we'll begin by simplifying and expanding the equation:

0.3(8) - 0.3(3x) = 3.2 - 0.8(x) + 0.8(7)

2.4 - 0.9x = 3.2 - 0.8x + 5.6

Next, we'll combine like terms:

-0.9x + 0.8x = 3.2 + 5.6 - 2.4

-0.1x = 6.4 - 2.4

-0.1x = 4

Finally, we'll solve for x by dividing both sides of the equation by -0.1:

x = 4 / -0.1

x = -40

Therefore, the solution to the equation 0.3(8 - 3x) = 3.2 - 0.8(x - 7) is x = -40.
