1. The problem asks us to check if any two numbers in the set add up to 10, then find the total sum of all numbers. 2. The numbers given are 4, 9, and 6. 3. We check pairs: - $4 + 9 = 13$ (not 10) - $9 + 6 = 15$ (not 10) - $4 + 6 = 10$ (this pair adds up to 10) 4. Since $4 + 6 = 10$, these are the groupable numbers. 5. Now, find the total sum: $$ (4 + 6) + 9 = 10 + 9 = 19 $$ 6. Therefore: - Groupable Numbers: $4 + 6$ - Total sum: $19$
