Question

0,3(х-1)-9,9=-0,15(х-4)!!!!​

Answer 1

Ответ:

Пошаговое объяснение:

0,3х-0,3-9,9=-0,15х+0,6.

0,3х+0,15х=0,6+10,2=10,8.

0,45х=10,8.

х=10,8/0,45.=24.

Answer 2

To solve the equation 0,3(x-1)-9,9=-0,15(x-4), we can simplify and solve for x step by step.

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

0.3(x-1) - 9.9 = -0.15(x-4)

0.3x - 0.3 - 9.9 = -0.15x + 0.6

Now, let's combine like terms:

0.3x - 10.2 = -0.15x + 0.6

Next, let's isolate the x terms on one side and the constant terms on the other side. We can do this by adding 0.15x to both sides of the equation:

0.3x + 0.15x - 10.2 = 0.6

Combining the x terms:

0.45x - 10.2 = 0.6

Next, let's isolate the x term by adding 10.2 to both sides:

0.45x = 0.6 + 10.2

0.45x = 10.8

Finally, divide both sides of the equation by 0.45 to solve for x:

x = 10.8 / 0.45

x ≈ 24

Therefore, the solution to the equation is x ≈ 24.
