Question

16/x=-28/35

Answer 1

\(\dfrac{16}{x}=\dfrac{-28}{35}\)

\(x=\dfrac{16\cdot35}{\left(-28\right)}\)

\(x=\dfrac{560}{\left(-28\right)}\)

\(x=-20\)

Answer 2

x=(-20)

Answer 3

`16/x = -28/38`

`=> x . (-28) = 16 . 38`

`=> x . (-28) = 608`

`=> x = 608 : (-28)`

`=> x = -608/28`

Answer 4

Answer 5

x = 20

Answer 6

\(\dfrac{16}{x}=\dfrac{-28}{35}\)

\(\dfrac{16}{x}=-\dfrac{4}{5}\)

\(5x\cdot\dfrac{16}{x}=5x\cdot\dfrac{-4}{5}\)

\(5\cdot16=x\cdot\left(-4\right)\)

\(80=x\left(-4\right)\)

\(80=-4x\)

\(\dfrac{80}{-4}=\dfrac{-4x}{-4}\)

\(-20=\dfrac{-4x}{-4}\)

\(-20=x\)

\(x=-20\)

vậy \(x=-20\)
