To solve the equation 2(x - 3) = 8, we begin by simplifying the equation. The first step involves distributing the 2 on the left side of the equation, which leads to:

2*x - 2*3 = 8

Simplifying gives us:

2x - 6 = 8

Next, we want to isolate the term with x. To do this, we add 6 to both sides of the equation:

2x - 6 + 6 = 8 + 6

This simplifies to:

2x = 14

Now, to solve for x, we divide both sides by 2:

x = 14 / 2

This results in:

x = 7.

It seems there was a misunderstanding regarding the options present and the value of x. The actual solution to the equation is x = 7, which doesn't match any of the provided answers. It's important to always verify calculations and ensure that the options align with so it’s vital to carefully compute each step methodically.
