Question

2,5-2,6(x-4)=2(4-0,5x)

Answer 1

Ответ:

3 целых 1/16

Пошаговое объяснение:

2,5-2,6(x-4)=2(4-0,5x)

2,5-2,6х+10,4=8-х

-2,6х+х=8-2,5-10,4

-1,6х=-4,9

х=-4,9/(-1,6)

х=3 целых 1/16

Answer 2

To solve the equation 2.5 - 2.6(x - 4) = 2(4 - 0.5x), you'll want to simplify and isolate the variable x. Here are the steps to solve it:

1. Distribute the constants on both sides of the equation:

   2.5 - 2.6x + 10.4 = 8 - x

2. Combine like terms on each side of the equation:

   -2.6x + 12.9 = 8 - x

3. To isolate x, you can add 2.6x to both sides of the equation and subtract 8 from both sides:

   -2.6x + 2.6x + 12.9 - 8 = -x + 2.6x - 8

4. This simplifies to:

   4.9 = 1.6x

5. Now, to solve for x, divide both sides by 1.6:

   x = 4.9 / 1.6

6. Calculate the value of x:

   x ≈ 3.06

So, the solution to the equation is approximately x ≈ 3.06.
