I'll solve this problem step by step, calculating the average for each set of numbers.

To find an average, I need to:
1. Add all the numbers together
2. Divide by how many numbers there are

Let me work through each row carefully:

Row 1:
- Left: 5, 10, 4, 7, 9 → Sum = 35, Count = 5, Average = 35 ÷ 5 = 7
- Right: 1, 9, 10, 4, 6 → Sum = 30, Count = 5, Average = 30 ÷ 5 = 6

Row 2:
- Left: 4, 8, 6, 5, 2 → Sum = 25, Count = 5, Average = 25 ÷ 5 = 5
- Right: 10, 15, 12, 4, 9 → Sum = 50, Count = 5, Average = 50 ÷ 5 = 10

Row 3:
- Left: 5, 3, 2, 6 → Sum = 16, Count = 4, Average = 16 ÷ 4 = 4
- Right: 10, 2, 2, 5, 1 → Sum = 20, Count = 5, Average = 20 ÷ 5 = 4

Row 4:
- Left: 12, 4, 3, 9, 12 → Sum = 40, Count = 5, Average = 40 ÷ 5 = 8
- Right: 1, 1, 2, 2, 4 → Sum = 10, Count = 5, Average = 10 ÷ 5 = 2

Row 5:
- Left: 10, 9, 10, 8, 8 → Sum = 45, Count = 5, Average = 45 ÷ 5 = 9
- Right: 10, 20, 20, 20, 30 → Sum = 100, Count = 5, Average = 100 ÷ 5 = 20

Row 6:
- Left: 5, 15, 10, 6, 14 → Sum = 50, Count = 5, Average = 50 ÷ 5 = 10
- Right: 10, 6, 2, 2 → Sum = 20, Count = 4, Average = 20 ÷ 4 = 5

Let me double-check my calculations:

Row 1: 5+10+4+7+9=35 ✓, 35÷5=7 ✓ | 1+9+10+4+6=30 ✓, 30÷5=6 ✓
Row 2: 4+8+6+5+2=25 ✓, 25÷5=5 ✓ | 10+15+12+4+9=50 ✓, 50÷5=10 ✓
Row 3: 5+3+2+6=16 ✓, 16÷4=4 ✓ | 10+2+2+5+1=20 ✓, 20÷5=4 ✓
Row 4: 12+4+3+9+12=40 ✓, 40÷5=8 ✓ | 1+1+2+2+4=10 ✓, 10÷5=2 ✓
Row 5: 10+9+10+8+8=45 ✓, 45÷5=9 ✓ | 10+20+20+20+30=100 ✓, 100÷5=20 ✓
Row 6: 5+15+10+6+14=50 ✓, 50÷5=10 ✓ | 10+6+2+2=20 ✓, 20÷4=5 ✓

All calculations verified!

Final Answer:
Row 1: 7, 6
Row 2: 5, 10
Row 3: 4, 4
Row 4: 8, 2
Row 5: 9, 20
Row 6: 10, 5
