a. the sum of three consecutive integers 
(first) + (second) + (third)
(x) + (x + 1) + (x + 2)
b. the sum of three consecutive odd integers
(first) + (second) + (third)
(x) + (x + 2) + (x + 4)
c. the sum of three consecutive even integers
(first) + (second) + (third)
(x) + (x + 2) + (x + 4)
d. The sum of three consecutive even integers is 24.
(first) + (second) + (third) = 24
(x) + (x + 2) + (x + 4) = 24
3x + 6 = 24
 6 6

3x = 18
3x/3 = 18/3
x = 6
The integers are 6 (from the x) , 8 (from the x + 2), and 10 (from the x + 4).
