Answer: 7 pigeons sitting on the branches,  5 pigeons under the tree

=12 in total

Step-by-step explanation:

Upper branch has x pigeons, lower has y.

Top branch said: "If one of you flies up to us our number will be double yours":

Well, if one of the bottom branch flies up, the top branch will have x+1 birds and the bottom will have (y−1). The top will have double the bottom, so:

x+1=2(y−1)

Top branch said: "If one of us flies down to you, our numbers will be equal":

Now, the top branch will have x−1 and the bottom y+1. The numbers should be equal:

x−1=y+1

The sum of 4 consecutive integers<br> is 354
fgiga [73]

Consecutive integers are numbers in a row on a number line (ie. 4,5,6 or 457,458,459 or 12341, 12342, 12343). They can also be negative as long as the problem doesn't specify if it's positive.

x= first integer

x+1= second integer

x+2= third integer

x+3= fourth integer

Add the four integers equal to 354.

x + (x+1) + (x+2) + (x+3)= 354

combine like terms

4x + 6= 354

subtract 6 from both sides

4x= 348

divide both sides by 4

x= 87 first integer

THREE REMAINING INTEGERS

x+1= 87 + 1= 88 second integer

x+2= 87 + 2= 89 third integer

x+3= 87 + 3= 90 fourth integer

ANSWER: The four consecutive integers are 87, 88, 89 and 90.

Hope this helps! :)
