# Maths inequalities question! Watch

1. It says find the greatest and the lowest integer values of n for which these inequalities are true

4≤3n-2<10 next question is 1<4n+5<20

I am really good at inequalities but this question got me confused do I have to replace the n or do I have to solve this inequalities first. It is really annoying and thank you

Split the inequalities and solve.

3n-3 <10,
1<4n+5
and

and find the set of numbers that satisfy all inequalities.
