Question

5n - 1 > 0 and 4n + 2 < 0

Answer 1

Isolate n in each inequality. Do you know how to do that?

Answer 2

You can think of how to do this by "reversing" the operations that are happening to n.

In the first, you have 5 times n - 1.

What is the opposite of subtracting 1?

Answer 3

\[5n-1>0\]
\[5n>1\]
\[n>\frac{1}{5}\]
\[4n+2<0\]
\[4n<-2\]
\[n<-\frac{1}{2}\]
which means, if the problem really says AND not OR then there is no solution

Answer 4

because there is no number that is both less than -1/2 and at the same time greater that 1/5
