Answer 1

a)3/4x-1/3=-5/2

   3/4x      =-5/2+1/3

   3/4x      =-1/12

       x       =-1/12:3/4

       x       =-1/9

b)2 1/3:x=-4/5

   7/3:x   =-4/5

         x   =7/3:-4/5

        x    =-35/12

c)x-4/5=3/10

   x      =3/10+4/5

   x      =11/10

Chúc bạn hok tốt

         

Answer 2

x-4/5 = 3/10

=> 10(x - 4) = 5.3

=> 10x - 40 = 15

=> 10x = 55

=> x = 5,5

Answer 3

\(\frac{3}{4}x-\frac{1}{3}=\frac{-5}{12}\)

\(\frac{3}{4}x=\frac{-5}{12}+\frac{1}{3}\)

\(\frac{3}{4}x=\frac{-1}{12}\)

\(x=\frac{-1}{12}:\frac{3}{4}\)

\(x=\frac{-1}{9}\)

Answer 4

\(2\frac{1}{3}:x=\frac{-4}{5}\)

\(\frac{7}{3}:x=\frac{-4}{5}\)

\(x=\frac{7}{3}:\frac{-4}{5}\)

\(x=\frac{-35}{12}\)

Answer 5

\(x-\frac{4}{5}=\frac{3}{10}\)

\(x=\frac{3}{10}+\frac{4}{5}\)

\(x=\frac{11}{10}\)
