Question

0,3(3х-1)+0,2=5(0,1-0,2х)-0,1

Answer 1

Ответ:

Пошаговое объяснение:

0,3(3х-1)+0,2=5(0,1-0,2х)-0,1

0,9x-0,3+0,2=0,5-x-0,1

0,9x+x=0,5-0,1+0,1

1,9x=0,5

x=0,5:1,9

x=1/2:19/10

x=1/2*10/19

x=5/19

Answer 2

0,3(3х-1)+0,2=5(0,1-0,2х)-0,1

Раскрываем скобки и решаем выражение:

0,9x-0,3+0,2-0,5+x+0,1 = 0

1,9x-0,5 = 0

1,9x = 0,5

x = $\frac{5}{19}$

Ответ: $\frac{5}{19}$.

Answer 3

Let's solve the given equation step by step:

0.3(3x - 1) + 0.2 = 5(0.1 - 0.2x) - 0.1

First, let's simplify the equation by distributing the terms:

0.9x - 0.3 + 0.2 = 0.5 - x - 1 + 0.1

Combine like terms on both sides:

0.9x - 0.1 = -0.5 - x

Now, let's isolate the x term on one side by adding x to both sides:

0.9x + x - 0.1 = -0.5 - x + x

Combine like terms:

1.9x - 0.1 = -0.5

Next, let's isolate the x term by adding 0.1 to both sides:

1.9x - 0.1 + 0.1 = -0.5 + 0.1

Simplifying further:

1.9x = -0.4

Finally, divide both sides of the equation by 1.9 to solve for x:

x = -0.4 / 1.9

Calculating the result:

x ≈ -0.2105

Therefore, the solution to the given equation is approximately x ≈ -0.2105.
