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