Question

tìm x:

11/12 - ( 2/5 + x) = 2/3

Answer 1

\(\frac{11}{12}-\left(\frac{2}{5}+x\right)=\frac{2}{3}\)

\(\frac{2}{5}+x=\frac{11}{12}-\frac{2}{3}\)

\(\frac{2}{5}+x=\frac{1}{4}\)

\(x=\frac{2}{5}-\frac{1}{4}\)

\(x=\frac{3}{20}\)

Answer 2

\(\frac{11}{12}-\left(\frac{2}{5}+x\right)=\frac{2}{3}\)

\(\Rightarrow\frac{2}{5}+x=\frac{1}{4}\)

\(\Rightarrow x=\frac{-3}{20}\)

Vậy \(x=\frac{-3}{20}\)

Answer 3

11/12 - ( 2/5 + x ) = 2/3

             2/5 + x = 11/12 - 2/3

             2/5 + x = 1/4

             x = 1/4 - 2/5

             x = -3/20

Answer 4

11/12 - ( 2/5 + x) = 2/3

 =>2/5+x=11/12-2/3

=>2/5+x=11/12-8/12

=>2/5+x=1/4

=>x=1/4-2/5

=>x=5/20-8/20

=>x=-3/20

Vậy x = -3/20

Answer 5

\(\frac{2}{5}\)+\(x\)=\(\frac{11}{12}\)-\(\frac{2}{3}\)

\(\frac{2}{5}\)+\(x\)=\(\frac{1}{4}\)

\(x\)          = \(\frac{1}{4}\)-\(\frac{2}{5}\)

\(x\)          =\(\frac{-3}{20}\)
