Question

1,2x+0,8( x-2,6)=11,92

Answer 1

1,2х+0,8(х-2,6)=11,92
1,2х+0,8х-2,08=11,92
2х-2,08=11,92
2х=11,92+2,08
2х=14
х=7

2x=14

x=7

Answer 3

To solve the equation 1.2x + 0.8(x - 2.6) = 11.92, you can follow these steps:

1. Distribute the 0.8 on the left side of the equation:

   1.2x + 0.8x - 0.8(2.6) = 11.92

2. Simplify the equation:

   2x + 0.8x - 2.08 = 11.92

3. Combine like terms:

   2.8x - 2.08 = 11.92

4. Add 2.08 to both sides of the equation to isolate the variable:

   2.8x = 11.92 + 2.08

   2.8x = 14

5. Finally, divide both sides by 2.8 to solve for x:

   x = 14 / 2.8

   x = 5

So, the solution to the equation is x = 5.
