You can put this solution on YOUR website! In a kennel, a cocker spaniel, a bulldaog, 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 exceeds the third by 10. How many puppies does each dog have? Use the 5 step method please, show work.
-----------------------------------
1st integer: x-1
2nd: x
3rd: x+1
-------
Equation:
x-1 + 2(x) = (x-1)+10
3x-1 = x+9
2x = 10
x = 5
-------------------
cockers: x-1 = 4
bulldogs: x = 5
greyhounds: x+1 = 6
----------------------
