Answer:
3 and 6
Step-by-step explanation:
Let the two numbers be a and b.
a > b
Sum of two numbers are 9 means,
a + b = 9 -------> eq 1.
Their difference is three means,
a - b = 3
a + b = 9
a - b = 3
_______
2a + 0 = 12
2a = 12
a = 12 / 2
a = 6
Substitute a = 6 in eq 1,
6 + b = 9
b = 9 - 6
b = 3
Therefore, the two numbers are 3 and 6.
