Answer 6

x = number of birds
y = number of cages

If you keep 1 bird per cage, there will be one bird outside of the cage
means:

y*1 +1 = x


If you keep two birds per cage, there will be one empty cage.
means:

y*2 - 1 = x

Answer 7

y*1 +1 = x
y*2 - 1 = x

Solve these two equations simultaneously
