Let's solve each equation step by step, indicating whether we add or subtract, and then find the value.

### Problem 10: $$ 8 + x = 42 $$
- To isolate $$ x $$, we need to subtract $$ 8 $$ from both sides.
- **Operation:** Subtract
- Calculation: 
  $$
  x = 42 - 8
  $$
- Result: 
  $$
  x = 34
  $$

### Problem 11: $$ w - 61 = 14 $$
- To isolate $$ w $$, we need to add $$ 61 $$ to both sides.
- **Operation:** Add
- Calculation: 
  $$
  w = 14 + 61
  $$
- Result: 
  $$
  w = 75
  $$

### Problem 12: $$ n - 81 = 67 $$
- To isolate $$ n $$, we need to add $$ 81 $$ to both sides.
- **Operation:** Add
- Calculation: 
  $$
  n = 67 + 81
  $$
- Result: 
  $$
  n = 148
  $$

### Problem 13: $$ m + 3.89 = 9.02 $$
- To isolate $$ m $$, we need to subtract $$ 3.89 $$ from both sides.
- **Operation:** Subtract
- Calculation: 
  $$
  m = 9.02 - 3.89
  $$
- Result: 
  $$
  m = 5.13
  $$

### Problem 14: $$ y + 2.4 = 6.75 $$
- To isolate $$ y $$, we need to subtract $$ 2.4 $$ from both sides.
- **Operation:** Subtract
- Calculation: 
  $$
  y = 6.75 - 2.4
  $$
- Result: 
  $$
  y = 4.35
  $$

### Problem 15: $$ c + \frac{5}{9} = \frac{8}{9} $$
- To isolate $$ c $$, we need to subtract $$ \frac{5}{9} $$ from both sides.
- **Operation:** Subtract
- Calculation: 
  $$
  c = \frac{8}{9} - \frac{5}{9}
  $$
- Result: 
  $$
  c = \frac{3}{9} = \frac{1}{3}
  $$

### Summary of Results:
- 10. $$ x = 34 $$ (subtract)
- 11. $$ w = 75 $$ (add)
- 12. $$ n = 148 $$ (add)
- 13. $$ m = 5.13 $$ (subtract)
- 14. $$ y = 4.35 $$ (subtract)
- 15. $$ c = \frac{1}{3} $$ (subtract)
- 10. $$ x = 34 $$ (subtract) - 11. $$ w = 75 $$ (add) - 12. $$ n = 148 $$ (add) - 13. $$ m = 5.13 $$ (subtract) - 14. $$ y = 4.35 $$ (subtract) - 15. $$ c = \frac{1}{3} $$ (subtract)
