Turn the question into equations form. The first "What" is x, the second "what" is y, and we have:
1) x * y = 18
2) x + y = -7
This is a system of linear equations. There are several ways to solve this, one of the more simpler ways, substitution, goes as follows:
Solve for x in equation 1
x = 18/y
Substitute x into equation 2
(18/y) + y = -7
Multiply y to both sides
18 + y2 = -7y
Move everything to one side
y2 + 7y + 18 = 0
This quadratic cannot be solved using factoring, and looking at the determinant (b2 - 4ac), we see that it has no solutions because it's negative.
