$$6x+20 = 4x+10$$
Answer
$$ x = -5 $$
Explanation
$$ \begin{aligned} 6x+20 &= 4x+10&& \text{move the $ \color{blue}{ 4x } $ to the left side and $ \color{blue}{ 20 }$ to the right} \\[1 em]6x-4x &= 10-20&& \text{simplify left and right hand side} \\[1 em]2x &= -10&& \text{ divide both sides by $ 2 $ } \\[1 em]x &= -\frac{10}{2}&& \\[1 em]x &= -5&& \\[1 em] \end{aligned} $$
