Mrs gray bought some eggs. she boiled one half of them and poached one fourth of the remainder . she had 9 eggs left. how many eggs did she buy?

To answer this item, we let x be the number of eggs in the beginning. The first half of the egg which were not boiled is represented through the equation is represented by x/2.

Next, the remainder of the egg which were not boiled nor poached is equal to 
             = (1/2)(3/4)x

Simplifying,
                 0.375x

Equating this to 9,
               0.375x = 9

The value of x from the equation is 24.

24 eggs
