cảm ơn mọi người đã giúp em
a, ĐKXĐ : x \(\ne\)-2
Ta có:
\(\frac{15}{x+2}=3\Leftrightarrow15=3\left(x+2\right)\)
\(\Leftrightarrow15=3x+6\Leftrightarrow3x=9\Leftrightarrow x=3\)( thõa mãn)
Vậy x =3
b, Ta có: \(541-\left(218+x\right)=73\Leftrightarrow-x=-250\Leftrightarrow x=250\)
c, ĐKXĐ : x \(\ne\)-1
Ta có: \(\frac{20}{x+1}=2\Leftrightarrow x+1=10\Leftrightarrow x=9\)( thõa mãn)
