\(\frac{4}{7}+x\times2=\frac{5}{3}\)
\(x\times2=\frac{5}{3}-\frac{4}{7}\)
\(x\times2=\frac{23}{21}\)
\(x=\frac{23}{21}:2\)
\(x=\frac{23}{42}\)
\(\frac{4}{7}+x\times2=\frac{5}{3}\)
\(x\times2=\frac{5}{3}-\frac{4}{7}\)
\(x\times2=\frac{23}{21}\)
\(x=\frac{23}{21}:2\)
\(x=\frac{23}{42}\)
Vậy x = 23/42
x*2=5/3-4/7
x*2=23/21
x =23/21:2
x =23/42
