Question

How do you solve -5n+ 16<-7n?

Answer 1

-5n+16<-7n
2n=<-16
n<-8

Answer 2

Hey!

First, let's write the problem.
$-5n+16\ \textless \ -7n$
Subtract $16$ from both sides.
$-5n+16-16\ \textless \ -7n-16$
$-5n\ \textless \ -7n-16$
Add $7n$ to both sides.
$-5n+7n\ \textless \ -7n-16+7n$
$2n\ \textless \ -16$
To get n by itself, we have to divide both sides by $2$.
$\frac{2n}{2}\ \textless \ \frac{-16}{2}$

This tells us that our final answer would be.
$n\ \textless \ -8$
