CONTINUE: INTEGERS. FIND THE INTEGERS

The first answer fails to consider that the problem says the sum of two consecutive
EVEN integers, so their difference is 2. Call them N and N+2.
Their sum is N + N+2
If you subtract 9 from the sum, that’s 2N + 2 – 9 or 2N – 7 and that equals
3 more than the larger, or N + 2 + 3 or N + 5.
If they are equal we can say: 2N – 7 = N + 5
Add 7 to both sides and get: 2N = N + 12
Subtract N from both sides: N = 12 and N + 2 = 14.
The integers are 12 and 14. They are two consecutive even integers.
To check, add them and subtract 9; we get 17, which is 3 more than 14.
So our answer of 12 and 14 is correct.

Y+(Y-1) -9 = Y+3
This is stating your question.
I don’t think I need to solve it.
It is very easy from this point.
