For this case we have the following equation:

$2 (x + 2) = x-4$

Applying distributive property to the terms within the parentheses on the left side of the equation we have:

$2x + 4 = x-4$

Subtracting "x" on both sides of the equation we have:

$2x-x + 4 = -4\\x + 4 = -4$

Subtracting 4 on both sides of the equation we have:

$x = -4-4\\x = -8$

Answer:

$x = -8$
