5+18/6-2x7=42 Place grouping symbols to make the equation true

Solution:
1. Given the expression: 5 + \frac{18}{6} - 2 \times 7
2. Calculate each operation step-by-step without grouping symbols to see where they might be needed to make the equation true as 42.
3. Original calculation without grouping:
- \frac{18}{6} = 3
- Expression becomes: 5 + 3 - 2 \times 7
- Calculate multiplication: 2 \times 7 = 14
- Continue calculation: 5 + 3 - 14 = -6
4. Try different grouping possibilities:
- Attempt placing grouping symbols: (5 + \frac{18}{6} - 2) \times 7 = 42
5. Check the new calculation:
- Inside grouping: 5 + \frac{18}{6} - 2 = 5 + 3 - 2 = 6
- Multiply by 7: 6 \times 7 = 42
6. The expression with grouping symbols to result in 42 is:
(5 + \frac{18}{6} - 2) \times 7 = 42
