Some birds were flying and met another bird, the bird said, "HELLO!! hundreds",the birds replied"we are not hundred, we need half plus you to make us 100

If your looking for how many birds there are, there are 49.

Step-by-step explanation: If the birds said they need half of 100 (that's 50) plus the other bird (that's 51 birds) then you need to subtract 51 from 101 and you get the answer 41.

I hope this helped you!

y = 3x - 5

Step-by-step explanation:

3x-y=5

-3x     -3x

-y= -3x + 5

divide each number by -1

-y/-1 = y

-3x/-1 = 3x

5/-1 = -5
