1/3x + 2/5(x+1) = 0
=> 1/3x + 2/5x + 2/5 = 0
=> 1/3x + 2/5x = -2/5
=> 11/15x = -2/5
=> x = -2/5 : 11/15
=> x = -2/5 . 15/11 = -6/11
Vậy x = -6/11
\(\frac{1}{3}x+\frac{2}{5}\left(x+1\right)=0\)
\(\frac{1}{3}x+\frac{2}{5}x+\frac{2}{5}=0\)
\(\frac{11}{15}x=0+\frac{2}{5}\)
\(\frac{11}{15}x=\frac{2}{5}\)
\(x=\frac{11}{15}\div\frac{2}{5}\)
\(x=\frac{11}{6}\)
Mik làm lộn nha !
\(\frac{1}{3}x+\frac{2}{5}\left(x+1\right)=0\)
\(\frac{1}{3}x+\frac{2}{5}x+\frac{2}{5}=0\)
\(\left(\frac{1}{3}+\frac{2}{5}\right)x+\frac{2}{5}=0\)
\(\frac{11}{15}x+\frac{2}{5}=0\)
\(\frac{11}{15}x=0-\frac{2}{5}\)
\(\frac{11}{15}x=\frac{-2}{5}\)
\(x=\frac{-2}{5}:\frac{11}{15}\)
\(x=\frac{-6}{11}\)
