n<-2/5

Explanation:

color(blue)(5/6 n-1/5<-8/15

This is an inequality. To solve this we need to isolate n by balancing both sides

rarr5/6 n-1/5<-8/15

Add 1/5 both sides

rarr5/6 n-1/5+color(red)(1/5)<-8/15+color(red)(1/5)

rarr5/6 n<-8/15+3/15

rarr5/6 n<-1/3

Divide both sides by 5/6

rarr5/6 n-:5/6<-1/3-:5/6

rarrn<-1/3*6/5

rarrn<-6/15

rArrn<-2/5=-0.4

Hope this helps!!! :)
