Question
$$4(3x+2) = 11x+18$$
Answer
$$ x = 10 $$
Explanation
$$ \begin{aligned} 4(3x+2) &= 11x+18&& \text{simplify left side} \\[1 em]12x+8 &= 11x+18&& \text{move the $ \color{blue}{ 11x } $ to the left side and $ \color{blue}{ 8 }$ to the right} \\[1 em]12x-11x &= 18-8&& \text{simplify left and right hand side} \\[1 em]x &= 10&& \\[1 em]x &= 10&& \\[1 em] \end{aligned} $$
