Question

2(х – 0.3) = 4х – 5,7

Answer 1

Ответ:

Пошаговое объяснение:

2x-0,6=4x-5,7

2x-4x=0,6-5,7

-2x=-5,1

2x=5,1

x=2,55

Answer 2

To solve the equation 2(x - 0.3) = 4x - 5.7 for the variable x, follow these steps:

1. Distribute the 2 on the left side of the equation by multiplying it with both terms inside the parentheses:

2(x - 0.3) = 2x - 0.6

Now, the equation becomes:

2x - 0.6 = 4x - 5.7

2. Next, isolate the variable terms (terms with x) on one side of the equation and the constant terms on the other side. You can do this by subtracting 2x from both sides:

2x - 2x - 0.6 = 4x - 2x - 5.7

This simplifies to:

-0.6 = 2x - 5.7

3. Now, add 5.7 to both sides of the equation to further isolate the variable:

-0.6 + 5.7 = 2x - 5.7 + 5.7

This simplifies to:

5.1 = 2x

4. Finally, divide both sides of the equation by 2 to solve for x:

(5.1) / 2 = (2x) / 2

x = 2.55

So, the solution to the equation 2(x - 0.3) = 4x - 5.7 is x = 2.55.
