Hello I need help with this question as fast as possible please , I am on my last few questions and I have been studying all day for my final exam for math tomorrow. It is past my bed time and I am exhausted . Thank you so much for understanding:))

Answer 1

Notice that:

`665.6=10.4*64.`

Therefore, if we divide the resulting equation of step 3 by 10.4 we get:

`\begin{gathered} (10.4x)/(10.4)=(665.6)/(10.4), \\ x=64. \end{gathered}`

Then the missing step is:

Divide both sides of the equation by 10.4.

Answer: Last option.
