Answer: Liam has 52 chairs.
Step-by-step explanation:
Let x= Number of chairs in each row.
If he arranges the chairs in 9 rows and 7 chairs left over.
Then total chairs = 9x+7
If he arranges the chairs in 7 rows and 17 left over.
Total chairs = 7x+17
Now,
Total chairs = 9(5)+7 = 45+7= 52
Hence, Liam has 52 chairs.
