Question

1/4+1/3:(2x-1)=(-5)

Answer 1

 

1/4+1/3:(2x-1)=(-5)

       1/3:(2x-1)=-5 - 1/4

       1/3:(2x-1)=-21/4

             2x-1=1/3:-21/4

             2x-1=-4/36

             2x   =-4/36+1

             2x   =59/36

               x   =59/36:2

               x   =59/126

        

 

  

 

Answer 2

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

          2x -1 = -15/3/4

          2x     = -14/3/4 

            x     = -7 /3/8

Answer 3

Mk lộn, sr, mk làm lại

\(\frac{1}{3}:\left(2x-1\right)=-5-\frac{1}{4}=-\frac{21}{4}\)

\(2x-1=\frac{1}{3}:-\frac{21}{4}=\frac{1}{3}.\frac{-4}{21}=-\frac{4}{63}\)

\(2x=-\frac{4}{63}+1=\frac{59}{63}\)

\(x=\frac{59}{63}:2=\frac{59}{63}.\frac{1}{2}=\frac{59}{126}\)
