Ta có \(x.\frac{7}{8}-x.\frac{3}{4}=\frac{2}{3}\)
\(\Rightarrow x.\left(\frac{7}{8}-\frac{3}{4}\right)=\frac{2}{3}\)
\(\Rightarrow x.\frac{1}{8}=\frac{2}{3}\)
\(\Rightarrow x=\frac{2}{3}.8\)
\(\Rightarrow x=\frac{16}{3}\)
Ta có : x * 7/8 - x * 3/4 = 2/3 .
=> x * ( 7/8 - 3/4 ) = 2/3 .
=> x * ( 7/8 - 6/8 ) = 2/3 .
=> x * 1/8 = 2/3 .
=> x = 2/3 * 1/8 .
=> x = 1/12 .
Vậy x = 1/12 .
x × 7/8 - x × 3/4 = 2/3
x × ( 7/8 - 3/4 ) = 2/3
x × ( 7/8 - 6/8 ) = 2/3
x × 1/8 = 2/3
x = 2/3 : 1/8
x = 2/3 × 8
x = 16/3
Vậy x = 16/3
