for simplicity sake i'm going to take away the 'billion term' we can add it back at the end let asia = x let africa = y let rest of world = z so first off x + y + z = 6.6 since the difference between x and y is 2 x-y = 2 and the last equation (1/2)x+(1/10) = z

you can use substitution here , or matrix operators (if you know how) to solve the variables x y and z. once you get numbers for x y and z tag the 'billion' behind them and you are left with your final answer! :)
