x * 4/3 - x *1/3 = 2/9
x * (4/3-1/3) = 2/9
x * 1 = 2/9
x = 2/9
\(x\cdot\frac{4}{3}-x\cdot\frac{1}{3}=\frac{2}{9}\)
\(x\cdot\frac{4-1}{3}=\frac{2}{9}\)
\(x\cdot1=\frac{2}{9}\)
\(x=\frac{2}{9}:1\)
\(x=\frac{2}{9}\)
x . 4/3 - x . 1/3 = 2/9
x . (4/3 - 1/3) = 2/9
x . 1 = 2/9
x = 2/9 : 1= 2/9
Chúc bạn học tốt!
