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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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