Question

1/2-2x=(-1/2)^3

Answer 1

=>1/2-2x=-1/8

=>2x=1/2+1/8=5/8

=>x=5/16

Answer 2

\(\dfrac{1}{2}-2x=\left(-\dfrac{1}{8}\right)\\ 2x=\dfrac{1}{2}-\left(-\dfrac{1}{8}\right)\\ 2x=\dfrac{4+1}{8}\\ 2x=\dfrac{5}{8}\\ x=\dfrac{5}{16}\)

Answer 3

`[41]`

` 1/2 - 2x = -1/8`

`2x = 1/2 + 1/8`

`2x = 5/8`

`x = 5/16`

Answer 4

\(\dfrac{1}{2}-2x=\left(\dfrac{-1}{2}\right)^3\)

\(\dfrac{1}{2}-2x=\dfrac{-1}{8}\)

        \(2x=\dfrac{1}{2}-\dfrac{-1}{8}\)

        \(2x=\dfrac{5}{8}\)

          \(x=\dfrac{5}{8}:2\)

          \(x=\dfrac{5}{8}.\dfrac{1}{2}\)

          \(x=\dfrac{5}{16}\)
