After using 30% of the total number of eggs, a cook still has 14 eggs left in his basket. Find the total number of eggs at the begging and number of eggs used

let 'x' be the number of eggs at the beginning 
    'y' be the number of eggs left
you're given that 14 eggs were left and that 30% was used therefore using that idea we can conclude that 14 is (100%-30%) of the total number of eggs or it is 70%
so we'll have the expression as:
14 = 0.70x
x = 14/0.70
x = 20 eggs
since there are 20 eggs at the beginning then you'll have the number of eggs left as,
y = x - 14
y = 20 - 14
y = 6 eggs
