$n = 18$ $n=18$

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

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

Collect terms

$5 n = 90$ $5n = 90$

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

$\frac{5 n}{5} = \frac{90}{5}$ $(5n)/5 = 90/5$

$n = 18$ $n = 18$

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