Question

2,5-(3x-2)-4-(2x+0,5)=-4 хелп​

Answer 1

Ответ: х = 0,8

Пошаговое объяснение:

1) відкриваємо скобки, 2,5-3х+2-4-2х-0,5=-4

2) зводимо подібні доданки,і перенесемо члени зі змінною у ліво, та без змінної до права, -5х=-4-2,5-2+4+0,5

3) вирішуємо праву частину, -5х=-4

4) шукаємо х, х = -4:(-5)=0,8

Answer 2

To solve the equation 2.5(3x - 2) - 4 - (2x + 0.5) = -4, you can follow these steps:

1. Distribute the 2.5 on the left side of the equation:

   7.5x - 5 - 4 - (2x + 0.5) = -4

2. Combine like terms on both sides of the equation. First, simplify the constants on the left side:

   (7.5x - 9.5) - (2x + 0.5) = -4

3. Now, distribute the negative sign on the right side:

   7.5x - 9.5 - 2x - 0.5 = -4

4. Combine like terms on both sides of the equation:

   (7.5x - 2x) - (9.5 + 0.5) = -4

5. Simplify further:

   5.5x - 10 = -4

6. Add 10 to both sides of the equation to isolate the term with the variable:

   5.5x = 6

7. Finally, divide both sides by 5.5 to solve for x:

   x = 6 / 5.5

Now, calculate the value of x:

x ≈ 1.0909

So, the solution to the equation is approximately x ≈ 1.0909.
