Question

giúp mình gấp nhé

a)x-1/4=2/5

b)4/3-x=-1/6

c)2x+1/4=-3/2

d)-5/3-2:x=7/6

e)(1-2x).1/3=-2/5

xin cám ơn

Answer 1

a=13/20 b=3/2 c -7/8 d -17/12 e 11/10 nha giúp bạn hok tôt 

Answer 2

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

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

   \(x\)          \(=\frac{13}{20}\)

\(\text{b)}\frac{4}{3}-x=\frac{-1}{6}\)

                \(x=\frac{4}{3}+\frac{1}{6}\)

                \(x=\frac{3}{2}\)

\(\text{c)}2x+\frac{1}{4}=\frac{-3}{2}\)

   \(2x\)         \(=\frac{-3}{2}+\frac{-1}{4}=\frac{-7}{4}\)

     \(x\)         \(=\frac{-7}{8}\)

\(\text{d)}\frac{-5}{3}-2:x=\frac{7}{6}\)

                    \(2:x=\frac{-5}{3}+\frac{-7}{6}=\frac{-17}{6}\)

                        \(x=\frac{-12}{17}\)

e)\(\left(1-2x\right).\frac{1}{3}=\frac{-2}{5}\)

    \(\left(1-2x\right)\)   \(=\frac{-2}{5}.3=\frac{-6}{5}\)

                \(2x\)       \(=1+\frac{6}{5}\frac{11}{5}\)

                  \(x\)        \(=\frac{11}{5}.\frac{1}{2}=\frac{11}{10}\)
