2.x+10/3=22/3
2.x=22/3-10/3
2.x=4
x=4:2
x=2
vậy x=2
Trả lời:
\(2x+\frac{31}{3}=7\frac{1}{3}\)
\(\Leftrightarrow2x+\frac{31}{3}=\frac{22}{3}\)
\(\Leftrightarrow2x=\frac{-9}{3}\)
\(\Leftrightarrow2x=-3\)
\(\Leftrightarrow x=\frac{-3}{2}\)
Vậy \(x=\frac{-3}{2}\)
Trả lời:
\(2x+3\frac{1}{3}=7\frac{1}{3}\)
\(\Leftrightarrow2x=4\)
\(\Leftrightarrow x=2\)
Vậy \(x=2\)
