Question

What is a number that when you divide it by 2 and subtract 3.8 from the quotient, you get 7?

Answer 1

Let the number x.

Then the number divided by 2 gives

`(x)/(2)`

Subtract 3.8 from the quotient gives

`(x)/(2)-3.8`

Hence,

`(x)/(2)-3.8=7`
`\begin{gathered} (x)/(2)-3.8=7 \\ (x)/(2)=7+3.8=10.8 \\ \Rightarrow x=2*10.8=21.6 \end{gathered}`

x = 21.6
