Answer:
4, 13
Step-by-step explanation:
Let's name these two numbers as a and b, where a is the larger number.
We know that:
a = b + 9
a + b = 17
This should be enough information to solve. Because of the transitive property, you can replace the a in the second equation with (b + 9) to solve for b:
(b + 9) + b = 17
2b + 9 = 17
2b = 8
b = 4
Now, since b, the smaller number, is 4, you can deduce that the larger number is 13, because 4 + 9 = 13.
