Question

3.4-2.6(x-3)＝5(8-0.2x)

Answer 1

Ответ:

-27,75

Объяснение:

3.4-2.6(x-3)＝5(8-0.2x)

3.4-2.6x-7,8＝40-1x

-2,6х+1х=40+7,8-3,4

-1,6х=44,4

х=44,4:(-1,6)

х=-27.75

Answer 2

-8

Объяснение:

3,4-2,6(х-3)=5(8-0.2х)

3.4-2.6х+7.8=40-х

3.6х=-28.8

х=-28.8/3.6

х=-8

Answer 3

Let's solve the given equation step by step:

3.4 - 2.6(x - 3) = 5(8 - 0.2x)

First, let's simplify both sides of the equation by distributing the coefficients:

3.4 - 2.6x + 7.8 = 40 - 1x

Combine like terms on both sides:

11.2 - 2.6x = 40 - x

Now, let's isolate the variables on one side and the constants on the other side:

-2.6x + x = 40 - 11.2

Combine like terms again:

-1.6x = 28.8

To solve for x, divide both sides of the equation by -1.6:

x = 28.8 / -1.6

Simplifying the right side:

x = -18

Therefore, the solution to the equation 3.4 - 2.6(x - 3) = 5(8 - 0.2x) is x = -18.
