Question

1) 2,5 - 3x = 3(x - 2,5) - 2;​

Answer 1

Ответ:x=2

Пошаговое объяснение:

2,5-3x=3(x-2,5) -2

2,5-3x=3x-7,5-2

-3x+(-3x)=-7,5-2-2,5

-6x=-12

x=-12/-6

x=2

Answer 2

To solve the equation 2.5 - 3x = 3(x - 2.5) - 2, we can follow these steps:

1. Distribute the 3 on the right side: 2.5 - 3x = 3x - 7.5 - 2. The equation becomes: 2.5 - 3x = 3x - 9.5.

2. Group like terms together: Move all terms with x to one side of the equation. Add 3x to both sides: 2.5 - 3x + 3x = 3x - 9.5 + 3x. Simplify: 2.5 = 6x - 9.5.

3. Isolate x: Move the constant term to the other side. Add 9.5 to both sides: 2.5 + 9.5 = 6x - 9.5 + 9.5. Simplify: 12 = 6x.

4. Solve for x: Divide both sides by 6 to isolate x. Divide by 6: 12/6 = 6x/6. Simplify: 2 = x.

Therefore, the solution to the equation 2.5 - 3x = 3(x - 2.5) - 2 is x = 2.
