Question

x*7/8-x*3/4=2/3 giải giúp mk với ạ (gấp)><

Answer 1

Ta có \(x.\frac{7}{8}-x.\frac{3}{4}=\frac{2}{3}\)

\(\Rightarrow x.\left(\frac{7}{8}-\frac{3}{4}\right)=\frac{2}{3}\)

\(\Rightarrow x.\frac{1}{8}=\frac{2}{3}\)

\(\Rightarrow x=\frac{2}{3}.8\)

\(\Rightarrow x=\frac{16}{3}\)

Answer 2

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 .   

Answer 3

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
