Question

1/2x - ( 2/3 + 1/3x ) = 0

Answer 1

1/2x-(2/3+1/3x)=0

1/2x-1/3x-2/3=0

1/2x-1/3x=2/3

1/6x=2/3

x=4( hơi tắt, mong bạn thông cảm)

Answer 2

\(\frac{1}{2x}-\left(\frac{2}{3}+\frac{1}{3x}\right)=0\)

<=> \(\frac{1}{2x}-\frac{2}{3}-\frac{1}{3x}=0\)

<=> \(\frac{1}{6x}-\frac{2}{3}=0\)

<=> \(\frac{1}{6x}=\frac{2}{3}\)

=>\(12x=3\)

=>x=\(\frac{1}{4}\)

Chúc bạn học tốt

Nhớ tích cho mình nhé
