Question

âm 3 phần 2 ( 5 trừ 1 phần 6 ) + 4 (x trừ 1 phần 2)=1

 

Answer 1

\(-\dfrac{3}{2}\left(5-\dfrac{1}{6}\right)+4.\left(x-\dfrac{1}{2}\right)=1\\ \dfrac{-3}{2}.\dfrac{29}{6}+4x-2=1\\ \dfrac{-29}{4}+4x-2-1=0\\ 4x=\dfrac{41}{4}\\ x=\dfrac{41}{16}\)

Answer 2

`-3/2 (5-1/6)+4(x-1/2)=1`

`-29/4 + 4(x-1/2)=1`

` 4(x-1/2)=1-(-29/4)`

` 4(x-1/2)=1+29/4`

`4(x-1/2)=33/4`

`x-1/2=33/4 . 1/4`

`x-1/2=33/16`

`x=33/16 + 1/2`

`x= 41/16`
