Answer 2

Ответ:

Пошаговое объяснение:

2(x-7)=-9

Раскрываем скобки, получается 2х-14= -9

Переносим 14 в правую часть с противоположным знаком 2х=-9+14

2х = 5

х = 2,5 или 5/2

Ответ: 2,5

Answer 3

Sure, I'd be happy to help you solve the equation!

The equation is:

2(x - 7) = -9

To solve for x, follow these steps:

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

2 * x - 2 * 7 = -9

Simplify:

2x - 14 = -9

Step 2: Now, isolate the term with x on one side of the equation. Add 14 to both sides to move the constant term to the other side.

2x - 14 + 14 = -9 + 14

Simplify:

2x = 5

Step 3: Finally, solve for x by dividing both sides by 2.

2x/2 = 5/2

Simplify:

x = 5/2

So, the solution to the equation is:

x = 2.5
