-x - 2 = 5/4

Answer 1

\(-x=\dfrac{5}{4}+2\)

\(-x=\dfrac{5}{4}+\dfrac{8}{4}\)

\(-x=\dfrac{13}{4}\)

\(x=-\dfrac{13}{4}\)

Answer 2

\(-x-2=\dfrac{5}{4}\)

       \(-x=\dfrac{5}{4}+2\)

       \(-x=\dfrac{13}{4}\)

          \(x=\dfrac{-13}{4}\)

Answer 3

`-x - 2 = 5/4`

`=> -x = 5/4 + 2`

`=> -x = 5/4 + 8/4`

`=> -x = 13/4`

vậy `x=-13/4`
