Given


-6=-20-v

- For -72 = 9(-20 - v):


\begin{gathered} -(72)/(9)=(9(-20-v))/(9) \\ -8=-20-v \end{gathered}

The equation is not equivalent

- For -90 = 15(-20 - v):


\begin{gathered} (-90)/(15)=(15(-20-v))/(15) \\ -6=-20-v \end{gathered}

The equation is equivalent

- For 5 * -6 = -100 - 5v:

Common factor 5


\begin{gathered} -30=5(-20-v) \\ (-30)/(5)=(5(-20-v))/(5) \\ -6=-20-v \end{gathered}

The equation is equivalent

- For 3 * -6 = -60 - 3v:

Common factor 3


\begin{gathered} -18=3(-20-v) \\ (-18)/(3)=(3(-20-v))/(3) \\ -6=-20-v \end{gathered}

The equation is equivalent

Answer:

-90 = 15(-20 - v)

5 * -6 = -100 - 5v

3 * -6 = -60 - 3v
