Question

6x-2(4x-1) = 7 решите

Answer 1

Ответ:

-2,5

Пошаговое объяснение:

6x - 8x + 2 = 7

-2x = 7 - 2

2x = -5

x = -2,5

Answer 2

$6x -8x + 2 = 7 \\ - 2x + 2 = 7 \\ - 2x = 5 \\ \\ x = - \frac{5}{2}$

Answer 3

Let's simplify the left-hand side of the equation first by distributing the -2:

6x - 2(4x-1) = 7

6x - 8x + 2 = 7

Next, let's combine like terms:

-2x + 2 = 7

Now, let's isolate the variable x by subtracting 2 from both sides:

-2x = 5

Finally, we'll solve for x by dividing both sides by -2:

x = -5/2

Therefore, the solution to the equation 6x - 2(4x-1) = 7 is x = -5/2.
