1) x = 23-20
=>x= 3
2)32-x=18
=>x=32-18
=>x=14
3)/2x+1/=8
=>2x+1=8
hoặc 2x+1=-8
=>x=7/2
hoặc x=-9/2
1/ Ta có: \(x+20=-\left(-23\right)\)
\(\Leftrightarrow x+20=23\)
\(\Leftrightarrow x=3\)
Vậy...
2/ Ta có: \(15-x+17=-\left(-6\right)+\left|-12\right|\)
\(\Leftrightarrow-x+32=18\)
\(\Leftrightarrow x=32-18=14\)
Vậy...
3/ Ta có: \(3-\left|2x+1\right|=\left(-5\right)\)
\(\Leftrightarrow\left|2x+1\right|=3-\left(-5\right)\)
\(\Leftrightarrow\left|2x+1\right|=8\)
\(\Leftrightarrow\orbr{\begin{cases}2x+1=8\\2x+1=-8\end{cases}}\)
\(\Leftrightarrow\orbr{\begin{cases}x=\frac{7}{2}\\x=-\frac{9}{2}\end{cases}}\)
Vậy...
