Question

8,6х-2(1,5х-7)=5,3-2,6х​

Answer 1

Ответ:

х = -3

Объяснение:

8,6х - 3х + 14 = 5,3 - 2,6х

2,9х = -8,7 (:2,9)

х = -3

Answer 2

8,6х-3х+14=5,3-2,6х
2,9х= -8,7(:2,9)
х= -3

Answer 3

To solve the equation 8.6x - 2(1.5x - 7) = 5.3 - 2.6x, you can follow these steps:

1. Distribute the -2 on the left side of the equation:

8.6x - 3x + 14 = 5.3 - 2.6x

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

(8.6x - 3x) + 14 = 5.3 - 2.6x

5.6x + 14 = 5.3 - 2.6x

3. Move all the terms with x to one side of the equation and the constants to the other side:

5.6x + 2.6x = 5.3 - 14

8.2x = -8.7

4. Now, isolate x by dividing both sides by 8.2:

x = -8.7 / 8.2

x ≈ -1.06 (rounded to two decimal places)

So, the solution to the equation is approximately x ≈ -1.06.
