Answer
$$x = - \frac{2}{3}$$
Work Step by Step
We use distributive property first:
$$2x + 6 + 2x = x + 4$$
Subtract $x$ on both sides to isolate the variable to one side of the equation:
$$2x + 6 + 2x - x = 4$$
Group like terms together:
$$(2x + 2x - x) + 6 = 4$$
Combine like terms:
$$3x + 6 = 4$$
Subtract $6$ from both sides to get the constants on one side of the equation:
$$3x = - 2$$
Divide both sides by $3$ to solve for $x$:
$$x = - \frac{2}{3}$$
