Объяснение:

0.2х-4=х-5

0,2х+х=4+5

1,2х=9

х=9/1,2

х=7.5

Answer 2

To solve the equation 0.5(0.4x - 8) = 5(0.2x - 1), follow these steps:

1. Distribute the constants on the left and right sides of the equation:

   0.5 * 0.4x - 0.5 * 8 = 5 * 0.2x - 5 * 1

2. Simplify both sides of the equation:

   0.2x - 4 = x - 5

3. To isolate the variable x on one side, you can subtract x from both sides of the equation:

   0.2x - x - 4 = -5

4. Combine like terms on the left side:

   -0.8x - 4 = -5

5. Now, add 4 to both sides of the equation to isolate the constant term:

   -0.8x = -5 + 4

6. Simplify the right side:

   -0.8x = -1

7. Finally, divide both sides by -0.8 to solve for x:

   x = -1 / -0.8

   x = 1.25

So, the solution to the equation is x = 1.25.
