Answer:

75, 77

Explanation:

Let the first odd number = 2x -1

Let the second odd number = 2x + 1

2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.

4x + 18 = 170 Subtract 18 from both sides.

4x = 170 - 18 Combine like terms on the right

4x = 152 Divide by 4

4x/4 = 152/4

x = 38

2 * 38 - 1 = 75

2 * 38 + 1 = 77
