Question

0,12-2,5x=4,2*(-3,5) решить уравнения

Answer 1

Сначала решим правую часть:

0,12-2,5х= -14,7

Теперь перенесем неизвестные (х) в левую часть, а известные - в правую. Если переносим через "равно", то знаки меняем на противоположные.

-2,5х= -14,7-0,12

-2,5х = -14,82

Делим на коэффициент перед переменной:

х = -14,82 / -2,5

х = 5,928

Ответ: х=5,928

Answer 2

To solve the equation, we need to find the value of x that makes the left side of the equation equal to the right side.

The equation is:

0.12 - 2.5x = 4.2 * (-3.5)

Step 1: Perform the multiplication on the right side of the equation: 0.12 - 2.5x = -14.7

Step 2: Move the constant term to the right side by adding 14.7 to both sides: 0.12 + 14.7 - 2.5x = 0

Step 3: Combine the constant terms on the left side: 14.82 - 2.5x = 0

Step 4: Now, we want to isolate x on one side of the equation. Let's get rid of the constant term on the left side by subtracting 14.82 from both sides:

14.82 - 14.82 - 2.5x = 0 - 14.82

This simplifies to:

-2.5x = -14.82

Step 5: Finally, isolate x by dividing both sides by -2.5:

x = -14.82 / -2.5

x = 5.928

So, the value of x that solves the equation is approximately 5.928.
