The equation in the image is:

$-2 + 2x - 2x = 6 + 2x$

Let's solve this step by step:

1. First, simplify both sides of the equation. On the left-hand side, $2x - 2x = 0$, so we are left with: $-2 = 6 + 2x$

2. Next, subtract 6 from both sides to isolate the term with $x$: $-2 - 6 = 2x$ Simplifying: $-8 = 2x$

3. Finally, divide both sides by 2 to solve for $x$: $x = \frac{-8}{2} = -4$

Thus, the solution is $x = -4$.
