Bài 1:
a)|x+1|-5=20-(-5)
\(\Leftrightarrow\)|x+1|=30
\(\Leftrightarrow\)\(\left[{}\begin{matrix}x+1=30\\x+1=-30\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}x=29\\x=-31\end{matrix}\right.\)
Vậy x=29 hoặc x=-31.
b)(-7)-|x+1|=32+(-11)
\(\Leftrightarrow\)|x+1|=28
\(\Leftrightarrow\left[{}\begin{matrix}x+1=28\\x+1=-28\end{matrix}\right.\)
\(\Leftrightarrow\left[{}\begin{matrix}x=27\\x=-29\end{matrix}\right.\)
Vậy x=27 hoặc x=-29.

Bạn xem lời giải của mình nhé:
Giải:
\(S=\frac{1}{5}+\left(\frac{1}{13}+\frac{1}{14}+\frac{1}{15}\right)+\left(\frac{1}{61}+\frac{1}{62}+\frac{1}{63}\right)\\ \frac{1}{13}< \frac{1}{12}\\ \frac{1}{14}< \frac{1}{12}\\ \frac{1}{15}< \frac{1}{12}\\ \frac{1}{61}< \frac{1}{60}\\ \frac{1}{62}< \frac{1}{60}\\ \frac{1}{63}< \frac{1}{60}\)
\(\Rightarrow\frac{1}{5}+\left(\frac{1}{13}+\frac{1}{14}+\frac{1}{15}\right)+\left(\frac{1}{61}+\frac{1}{62}+\frac{1}{63}\right)< \frac{1}{5}+\left(\frac{1}{12}+\frac{1}{12}+\frac{1}{12}\right)+\left(\frac{1}{60}+\frac{1}{60}+\frac{1}{60}\right)\)
\(\Rightarrow A< \frac{1}{5}+\frac{1}{12}.3+\frac{1}{60}.3\\ \Rightarrow A< \frac{1}{5}+\frac{1}{4}+\frac{1}{20}\\ \Rightarrow A< \frac{4+5+1}{20}\\ \Rightarrow A< \frac{1}{2}\left(đpcm\right)\)
Chúc bạn học tốt!
