Question

0,5(0,5 x-5,7)=3,5x+1,5​

Answer 1

Ответ:

Пошаговое объяснение:

0,25х-2,85=3,5х+1,5.

3,5х-0,25х=-1,5-2,85.

3,25х=-4,35.

х=-4,35/3,25 = 1  110/325=1  22/65≈1,34

Answer 2

To solve the equation 0.5(0.5x - 5.7) = 3.5x + 1.5, we can follow these steps:

1. Distribute 0.5 to the terms inside the parentheses: 0.25x - 2.85 = 3.5x + 1.5

2. Rearrange the equation to isolate the variables on one side: 0.25x - 3.5x = 1.5 + 2.85

   Simplifying the right side: -3.25x = 4.35

3. Divide both sides of the equation by -3.25 to solve for x: x = 4.35 / -3.25

   Evaluating the division: x ≈ -1.338

Therefore, the solution to the equation 0.5(0.5x - 5.7) = 3.5x + 1.5 is x ≈ -1.338.
