4 bilinmeyen oldugu icin 4 denklem gerekli.
t(x+1)=12x(z+1)=14z(y+1)=15y(t+1)=17
Mathematica ile cozum..
Solve[{t (x + 1) == 12, x (z + 1) == 14, z (y + 1) == 15, y (t + 1) == 17}, {x, y, z, t}, PositiveReals]
{x -> 4, y -> 5, z -> 5/2, t -> 12/5}
{x→4,y→5,z→52,t→125}
Burdan da |AB|=10 ve |AD|=5910=5.9 cikar.
