Question

How do you solve `39 = n/5 - 21`?

Answer 1

`n = 300`

Explanation:

the first thing that you want to do is eliminate the fractions. to do so, every variable has to be multiplied by the denominator.

`(39 xx 5) = ( n/5 xx 5) - (21 xx 5)`

`195 = n - 105`

isolate the `n` by adding `105` to both sides

`300 = n`

then reverse for flow

`n = 300`
