Question

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

 

Ai giải giúp mình,mk đg cần gấp

Answer 1

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

=> \(-x+\frac{1}{3}=2x+\frac{1}{2}\)

=> \(-x-2x=\frac{1}{2}-\frac{1}{3}\)

=> \(-3x=\frac{1}{6}\)

=> \(x=\frac{1}{6}:\left(-3\right)\)

=> \(x=-\frac{1}{18}\)
