Bài 1: First task:
Let \(x\) be the number of sparrows on the first lamp post at first. (\(x\) is a positive integer).
\(\Rightarrow16-x\)is the number of sparrows on the second lamp post at first.
We have: \(x-2+3=16-x+2-3\Leftrightarrow2x=14\Leftrightarrow x=7\)
Hence there are 7 sparrows on the first lamp post at first, 9 sparrows on the second lamp post at first.
