Question

(2х - 1,2) : 0,6 = 21,1;

Answer 1

Ответ:

х = 6.93

Пошаговое объяснение:

(2х -  1.2) : 0.6 = 21.1

2х - 1.2 = 21.1  * 0.6

2х - 1.2 = 12.66

2х = 1.2 + 12.66

2х = 13.86

х =  13.86 : 2

х = 6.93

Проверка:

(2 * 6.93 -  1.2) : 0.6 = 21.1

21.1 = 21.1

Answer 2

It seems like you're trying to solve an equation, but the notation you've used is a bit unclear. Let me clarify what I understand from your expression:

(2x - 1.2) / 0.6 = 21.1

To solve for x, you can follow these steps:

1. Multiply both sides of the equation by 0.6 to isolate the expression (2x - 1.2) on the left side:

   2x - 1.2 = 0.6 * 21.1

2. Calculate the right side:

   2x - 1.2 = 12.66

3. Add 1.2 to both sides to isolate 2x:

   2x = 12.66 + 1.2 2x = 13.86

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

   x = 13.86 / 2 x = 6.93

So, the solution to the equation (2x - 1.2) / 0.6 = 21.1 is x = 6.93.
