$n=18$

Rearrange the equation so that the $n$ term is by itself, by adding $5$ to both sides.

$-5 + 5n +5 = 85 + 5$

Collect terms

$5n = 90$

Divide by the coefficient of $n$ on both sides to leave a single $n$ . In this case, we divide by $5$ .

$(5n)/5 = 90/5$

$n = 18$

How do you solve -5+ 5n = 85-5+ 5n = 85?
