Question

tìm x

2.(1/2x-1/3)+3/2=1/4

Answer 1

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

`2 .  ( 1 / 2 x - 1 / 3 ) = 1 / 4 - 3 / 2`

`2 . ( 1 / 2 x - 1 / 3 ) = [-5] / 4`

`1 / 2 x - 1 / 3 = [-5] / 4 : 2`

`1 / 2 x - 1 / 3 = [-5] / 8`

`1 / 2 x = [-5] / 8 + 1 / 3`

`1 / 2 x = [-7] / 24`

`x =[-7] / 24 : 1 / 2`

`x = [-7] / 12`

Answer 2

\(\left(\dfrac{1}{2}x-\dfrac{1}{3}\right)+\dfrac{3}{2}=\dfrac{1}{4}\\ \dfrac{1}{2}x-\dfrac{1}{3}=\dfrac{1}{4}-\dfrac{3}{2}\\ \dfrac{1}{2}x-\dfrac{1}{3}=\dfrac{-5}{4}\\ \dfrac{1}{2}x=\dfrac{-5}{4}+\dfrac{1}{3}\\ \dfrac{1}{2}x=\dfrac{-11}{12}\\ x=\dfrac{-11}{12}:\dfrac{1}{2}\\ x=\dfrac{-11}{12}.\dfrac{2}{1}\\ x=\dfrac{-11}{6}\)

Answer 3

\(2\left(\dfrac{1}{2}x-\dfrac{1}{3}\right)+\dfrac{3}{2}=\dfrac{1}{4}\\ 2\left(\dfrac{1}{2}x-\dfrac{1}{3}\right)=\dfrac{1}{4}-\dfrac{3}{2}\\ 2\left(\dfrac{1}{2}x-\dfrac{1}{3}\right)=-\dfrac{5}{4}\\ \dfrac{1}{2}x-\dfrac{1}{3}=\left(-\dfrac{5}{4}\right):2\\ \dfrac{1}{2}x-\dfrac{1}{3}=-\dfrac{5}{8}\\ \dfrac{1}{2}x=\left(-\dfrac{5}{8}\right)+\dfrac{1}{3}\\ \dfrac{1}{2}x=-\dfrac{7}{24}\\ x=\left(-\dfrac{7}{24}\right):\dfrac{1}{2}\\ x=-\dfrac{7}{12}\)

Vậy `x=-7/12`

Answer 4

Answer 5

2.(1/2x-1/3)+3/2=1/4

2.(1/2x-1/3)=1/4-3/2

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

1/2x-1/3=-5/4÷2

1/2x-1/3=-5/8

1/2x=-5/8+1/3

1/2x=-7/24

       x=-7/24÷1/2

       x-7/12

Đó nha bạn
