Let a, b and c be positive integers. The sum of 160 and the square of a is equal the sum of 5 and the square of b. The sum of 320 and the square of a is equal to the sum of 5 and the square of c, a is

Let a, b and c be positive integers. The sum of 160 and the square of a is equal the sum of 5 and
the square of b. The sum of 320 and the square of a is equal to the sum of 5 and the square of b.
Find a.

Let x,y be the positive integers such that \(3x^2+x=4y^2+y\) . Prove that x-y is a perfect integer.

Number 6 is written as sum of two positive integers in three different ways: $6=1+5=2+4=3+3.$ (order does NOT matter). That is, there are exactly three different pairs of positive integers that add to make six. How many pairs of positive integers that add to make 1000?
