Two bears are in the forest
Number of bears in the forest = 2
One of the bears invites all his friends over.
Let the number of friends come = x
Now there are 17 bears
i.e. Number of bears in the forest + Number of friends = 17
Susbatitute the value and solve:
2 + x = 17
x = 17 - 2
x = 15
Number of friends come = 15
Answer : Number of bears came over are 15
