Henry made up a problem about three consecutive odd integers. He said, “The first decreased by the third equals the second decreased by 9.” What integers did he have in mind?

11, 13, 15

Let the first integer be x.  The second integer is (x + 2) and the third integer is (x + 4).

x - (x + 4) = (x + 2) - 9

4 = x - 7

x = 11

Now, just substitute

11, 13, 15

Step-by-step explanation:

Let the first integer be x.  The second integer is (x + 2) and the third integer is (x + 4).

x - (x + 4) = (x + 2) - 9

4 = x - 7

x = 11

Now, just substitute
