How do it more fast?

#include <iostream>
using namespace std;

int main()
{
    int x, y, c;

    cin >> x >> y >> c;

    if((x + y) < c)
    {
        cout << "Impossible" << endl;
    }
    else
    {
        for(int i = 0; i <= x; i++)
        {
            for(int j = 0; j <= y; j++)
            {
                if((i + j) == c)
                {
                    cout << i << " " << j << endl;
                    return 0;
                }
            }
        }
    }
}
