x=advertisement portion of a 60 minute program
4x = entertainment portion of a 60 minute program
x+4x=60
5x=60
x=12 4x12=48
entertainment=48 minutes
advertisement =12 minutes

Take 'x' to be the number of minutes in a portion.
So, you have 4 times x for the entertainment portion and just x for the advertisement portion. These two add to give you 60 minutes in total.
4x+x=60
5x = 60
x = 60/5 = 12
Since x is for advertisement potion, x is going to be 12 minutes.

Let e = entertainment
Let a= advertisement
e = 4a
a + e = 60
a + 4a = 60
5a = 60
a= 12
12 minutes is the answer

60 (min.)= x (ad. portion)+ 4x (entertainment portion)
60=x+4x
60=5x
X=12
ad. portion=12 min.
entertainment portion=48 min.
