You can put this solution on YOUR website!
Let x = video sales
2x + .27 = video rental

x + 2x + .27 = 9.81
3x +.27 = 9.81
3x + .27 -.27 = 9.81-.27
3x = 9.54
x= $3.18 billion
2x +.27 = 6.36 + .27 = $6.63 billion

Check: Does it add up to $9.81 billion?
$3.18 billion + $6.63 billion = $9.81 billion!
