Answer
$$ x = 7 $$
Explanation
$$ \begin{aligned} 4x-2(x+3) &= 8&& \text{simplify left side} \\[1 em]4x-(2x+6) &= 8&& \\[1 em]4x-2x-6 &= 8&& \\[1 em]2x-6 &= 8&& \text{ move -6 to the right } \\[1 em]2x &= 8+6&& \\[1 em]2x &= 14&& \text{ divide both sides by $ 2 $ } \\[1 em]x &= \frac{14}{2}&& \\[1 em]x &= 7&& \\[1 em] \end{aligned} $$
