(-5 + x) * y = - 90;

1. y = 1 = > x = - 85; or, y = - 1 = > x = 95;

2. y = 2 = > x = - 40; or, y = - 2 = > x = 50;

3. y = 3 = > x = - 25; or, y = - 3 = > x = 40;

4. y = 5 = > x = - 13; or, y = - 5=> x = 23;

5. y = 6 = > x = - 11; or, y = - 6 = > x = 20;

6. y = 9 = > x = - 5; or, y = - 9=> x = 15;

7. y = 10 = > x = - 4; or, y = - 10 = > x = 14;

8. y = 15 = > x = - 3; or, y = - 15=> x = 13;

9. y = 16 = > x = 0; or y = - 16 = > x = 10;

10. y = 30 = > x = 2; or, y = - 30=> x = 8;

11. y = 90 = > x = 4; or, y = - 90 = > x = 6;
