1 Burger + 1 Fries = 6 dollars, so 5 Burger + 5 Fries = 30 dollars.
Given 5 Burgers + 10 Drinks = 30 dollars, 5 Fries =10 Drinks.
Given 1 fries -1 Drink = 1 dollar, 5 Fries - 5 Drink =5 dollars.
Knowing 5 Fries = 10 Drinks, by rearranging the equation, 5 Fries - 10 Drinks = 0 dollars.
Solving:
5 Fries -5 Drink=5 Dollars
5 Fries -10 Drink = 0 Dollar
5 Drink = 5 Dollar
1 Drink= 1 Dollar
Knowing 1 Fries cost 1 Dollar more than Drink,
1 Fries = 2 Dollars
Since 1 Burger + 1 Fries = 6 Dollars, 1 Burger = 4 Dollars
Hence, 1 Burger + 1 Fries + 1 Drink= 1+2+4=7 Dollars

Definitely not easy. My answer may be a bit abstract, so try to draw out my equations. This will really help you to fully understand as opposed to giving you everything directly.
