You can put this solution on YOUR website! In a kennel, a cocker spaniel, a bulldog, and a greyhound all give birth to litters.
The number of pups in the litters are consecutive integers (in the order: cocker spaniel, bulldog, greyhound.)
The first integer increased by twice the second exceed the third by 10.
How many poppies does each dog have?
----------------------------
Equations:
1st: x-1
2nd: x
3rd: x+1
-----------------
(x-1)+2x = (x+1) + 10
3x -1 = x + 11
2x = 12
x = 6
-------------
1st = x-1 = 5
2nd = x = 6
3rd = x+1 = 7
