Question

In a 30-minutes television show, The number of minutes of programming is six more than twice the number of minutes of advertisements. How many minutes of programming is there

Answer 1

You have x number of minutes of advertisements.  Programming is 6 minutes more than 2 times the ads so it can be expressed as
X = Ad time
2X+6= Programming
Total = 30

X+2x+6=30
Simplified is 3x + 6 = 30
Subtract 6 from both sides 3X = 24
Divide both sides by 3 and X=8

Since X is ad time we know that ad time is 8 minutes
Programming is 2X+6 which is 2(8)+6 = 22 minutes

I hope that helps
