Ghi rõ đề ra nhé bạn! Ghi thế không ai hiểu!

1. interested in collecting stamps

2. which book I bought for her/him

3. not met Tom's uncle for 20 years

4. an interesting novel that I read it twice

Em nghĩ là ''Vợ nhặt'' :> Chúc anh chị thi tốt!

Trình bày ra nhé!

\(\left|x+5\right|=x+5\Leftrightarrow\left[{}\begin{matrix}x+5=x+5\\-x-5=x+5\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}0=0\left(ld\right)\\2x=-10\end{matrix}\right.\Leftrightarrow x=-5\) 

Vậy \(x=-5\)

\(pt\Leftrightarrow\left[{}\begin{matrix}-5x=\dfrac{5}{3}\\-5x=-\dfrac{5}{3}\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=-\dfrac{1}{3}\\x=\dfrac{1}{3}\end{matrix}\right.\Leftrightarrow x=\pm\dfrac{1}{3}\)

Vậy ........
