"If one of you comes to our tree, then our population will be double that of yours."
So [tex]A+1 =2\times (B-1)
A+1 = 2B - 2[/tex]
"If one of you comes here, then our population will be equal to that of yours." A − 1 = B + 1
Rearranging these to make A the subject gives:
A = 2 B − 3 A = B + 2
Then solve for B:
2 B − 3 = B + 2 B = 5
Substitute B back in to an equation:
A = B + 2 A = 5 + 2 A = 7
So there are seven birds in A, and 5 birds in B
Tree A has 7 birds and Tree B has 5 birds. This was determined using two mathematical statements based on the behavior of the birds. By setting up and solving the equations, we found the population counts for each tree.
