Answer 3

Just read the words and write as symbols.

The number of apples in an apple tree
n
after subtracting by 6,
n-6
multiplying by 6,
(n-6)*6
dividing by 6,
(n-6)*6/6
equals 6.
(n-6)*6/6 = 6
n-6 = 6
n = 12

books = x
a = x/2 + 1
b = (x-a)/2 + 2
c = (x-a-b)/2 + 3
x-a-b-c = 3
make all the right substitutions, and you wind up with
x = 58
a = 30
b = 16
c = 9
