To solve, let's set this word problem up as an equation. The first sentence says that the product of two integers is 72. In other words,
a x b = 72
The first part of the second sentence says that one integer is -18. So, to find the other integer, replace -18 with one of the letters in the equation:
a x b = 72: -18 x b = 72
Now, divide both sides of the equal sign by -18. This will allow us to get b all by itself:
%28-18%2Ab%29%2F%28-18%29+=+72%2F%28-18%29
This results in
b = -4
So, the other integer is -4
