The answers are B and C.
Hope this helps!
Integers are numbers without decimals
The integers could you have multiplied are 9 and 2
Let the numbers be x and y
So, we have:

Increase x by 1 and reduce y by 1.
So, we have

Open brackets

Subtract xy from both sides

Collect like terms


Rewrite as:

The above means that, the difference between the integers is 7.
There are several integers that fit the above <em>description</em>;
One possibility is: 9 and 2
