A chipmunk hid 3 acorns in each holes and squirrel hid 4 acorns in each of the holes but they hid the same number of acorns and the squirrel had 4 fewer holes
Let the number of holes that the Chipmunk used =N
And the number of holes that the Squirrel used =N - 4
But we have:
3N = 4[N - 4]
3N = 4N - 16
N=16 holes that the Chipmunk used.
3 x 16 = 48 acorns that the Chipmunk hid.
16 - 4 = 12 holes that the Squirrel used
12 x 4 =48 acorns that the Squirrel hid.
