Question

0,72:(0,2-х)=1,5 пж.

Answer 1

0,72 : (0,2 - х) = 1,5

0,2 - х = 0,72 : 1,5

0,2 - х = 0,48

х = 0,2 - 0,48

х = - 0,28

- - - - - - - - -

Проверка:

0,72 : (0,2 - (-0,28)) = 1,5

0,72 : (0,2 + 0,28) = 1,5

0,72 : 0,48 = 1,5

1,5 = 1,5

Answer 2

To solve the equation, we need to isolate the variable 'x' on one side of the equation. Here are the steps to do so:

1. First, we'll distribute the factor (0,72) to the expression (0,2-x) by multiplying:

   0,72 * 0,2 - 0,72 * x = 1,5

   This simplifies to:

   0,144 - 0,72x = 1,5

2. Next, we'll isolate the variable 'x' by subtracting 0,144 from both sides of the equation:

   -0,72x = 1,5 - 0,144

   -0,72x = 1,356

3. Finally, we'll solve for 'x' by dividing both sides by -0,72:

   x = 1,356 / (-0,72)

   This simplifies to:

   x ≈ -1,88

Therefore, the solution to the equation 0,72:(0,2-x)=1,5 is x ≈ -1,88.
