Question

tim X:

3/2x4/7-X=2/3

giúp mình với nhanh lên mình cần gấp lắm.

Answer 1

\(\frac{3}{2}\times\frac{4}{7}-x=\frac{2}{3}\)

\(\frac{6}{7}-x=\frac{2}{3}\)

\(x=\frac{6}{7}-\frac{2}{3}\)

\(x=\frac{18}{21}-\frac{14}{21}\)

\(x=\frac{4}{21}\)

Answer 2

\(\frac{3}{2}\chi\frac{4}{7}-x=\frac{2}{3}\)

\(\frac{6}{7}-x=\frac{2}{3}\)

\(x=\frac{6}{7}-\frac{2}{3}\)

\(x=\frac{4}{21}\)
