FindInstance

FindInstance[expr, vars] finds an instance of vars that makes the statement expr be True.

Examples

Find an integer solution:

FindInstance[x^2 + y^2 == 25, {x, y}, Integers]
(* {{x -> 0, y -> -5}} *)

Find multiple instances:

FindInstance[x^2 < 10, x, Integers, 5]
(* {{x -> -3}, {x -> -2}, {x -> -1}, {x -> 0}, {x -> 1}} *)
