Answer 2

To solve the given equation, let's simplify and solve for x:

$-2 \cdot (x+6) + 15 = - (2x+4) + 13$

First, distribute the -2 on the left side and the -1 on the right side:

$-2x - 12 + 15 = -2x - 4 + 13$

Combine like terms:

$-2x + 3 = -2x + 9$

Now, move all terms involving x to one side of the equation and the constants to the other side:

$-2x + 2x + 3 = 9$

Simplify:

$3 = 9$

The equation is inconsistent, and there is no solution. This means that there is no value of x that satisfies the equation. If you made a mistake in writing down the equation or if there's more information/context to consider, please double-check the equation.
