Question

Can you solve the inequality of -50 < 5n + -5 < 30

Answer 1

We have the inequality
\[-50<5n+-5<30\]
it's actually
\[-50<5n-5<30\]
I'll guide you, would you follow?

Answer 2

Sure

Answer 3

Add 5 to all the sides

Answer 4

Can you show me how to do it, then I'll figure it out on the next one.

Answer 5

sure !
\[-50<5n-5<30\]
Add 5 to all the sides
\[-50+5<5n-5+5<30+5\]
so we get
\[-45<5n+0<35\]
or
\[-45<5n<35\]
Now we want the range in terms of n, so divide all sides by 5
\[\frac{-45}{5}<\frac{5n}{5}<\frac{35}{5}\]
we get
\[-9<n<7\]
this is our answer
