Question

Tìm x:

\(\dfrac{1}{2}\)x + \(\dfrac{-5}{12}\)= \(\dfrac{-1}{3}\)

Answer 1

`1/2x + (-5)/12 = (-1)/3`

`1/2x - 5/12 = -1/3`

`1/2 x = -1/3 + 5/12`

`1/2 x = -4/12 + 5/12`

`1/2 x = 1/12`

`x=1/12 : 1/2`

`x=1/12 xx 2`

`x=2/12`

`x=1/6`

Answer 2

\(\dfrac{1}{2}x=-\dfrac{1}{3}+\dfrac{5}{12}\\ \dfrac{1}{2}x=\dfrac{-1.4+5}{12}\\ \dfrac{1}{2}x=\dfrac{1}{12}\\ x=\dfrac{1}{12}:\dfrac{1}{2}\\ x=\dfrac{1}{12}.\dfrac{2}{1}\\ x=\dfrac{1}{6}\)

Answer 3

\(\dfrac{1}{2}x=\dfrac{-1}{3}-\dfrac{-5}{12}\)

\(\dfrac{1}{2}x=\dfrac{1}{12}\)

\(x=\dfrac{1}{12}:\dfrac{1}{2}\)

\(x=\dfrac{1}{6}\)

vậy x = 1/6
