$n = 300$ $n = 300$

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

$(39 \times 5) = (\frac{n}{5} \times 5) - (21 \times 5)$ $(39 xx 5) = ( n/5 xx 5) - (21 xx 5)$

$195 = n - 105$ $195 = n - 105$

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

$300 = n$ $300 = n$

then reverse for flow

$n = 300$ $n = 300$
