Answer:
9
Step-by-step explanation:
Let the number be n.
Then: 4n + 15 = 6n - 3
Subtract 4n from both sides, obtaining: 15 = 2n - 3
Now add 3 to both sides, obtaining 18 = 2n. Then n = 9.

Answer:
Step-by-step explanation:
Let's say the number "n" were the largest multiple of 9. But then:
Consider n + 9. n is itself a multiple of 9, so n = 9k, so n + 9 = 9(k + 1), so n + 9 is also a multiple of 9, and n + 9 is larger than n.
So there can't be a largest multiple of 9 (or any number).
