`\qquad |2x-1|=x+5` ĐK: `x>=-5`
`<=>`\(\left[ \begin{array}{l}2x-1=x+5\\2x-1=-x-5\end{array} \right.\)
`<=>`\(\left[ \begin{array}{l}2x-x=5+1\\2x+x=-5+1\end{array} \right.\)
`<=>`\(\left[ \begin{array}{l}x=6\\3x=-4\end{array} \right.\)
`<=>`\(\left[ \begin{array}{l}x=6(\text{tm})\\x=\dfrac{-4}{3}(\text{tm})\end{array} \right.\)
Vậy `S={6;-4/3}`
`->` Tổng của chúng là `6-4/3=14/3`
`->` Chọn A
