Answer 1

х=1

0,5(4-х)-1.25(1+х)=-1

ответ х=1

Answer 2

To solve the equation 0.5(4-x) - 1.25(1+x) = -1, we can follow these steps:

1. Distribute the coefficients: 2 - 0.5x - 1.25 - 1.25x = -1

2. Combine like terms: (2 - 1.25) - (0.5x + 1.25x) = -1 0.75 - 1.75x = -1

3. Move the constant term to the other side of the equation: 0.75 = -1 + 1.75x

4. Simplify the right side: 0.75 = 1.75x - 1

5. Add 1 to both sides: 0.75 + 1 = 1.75x

   1.75 = 1.75x

6. Divide both sides by 1.75: 1.75 / 1.75 = x

   1 = x

Therefore, the solution to the equation 0.5(4-x) - 1.25(1+x) = -1 is x = 1.
