Let us say, the numbers are "a" and "b"
their sum is -13
a + b = -13
their product is 40
a * b = 40
![\bf \begin{cases} a+b=-13\\ a\cdot b=40\implies b=\frac{40}{a}\\ then\\ ------------\\ a+\boxed{b}=-13\implies a+\boxed{\frac{40}{a}}=-13 \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Bcases%7D%0Aa%2Bb%3D-13%5C%5C%0Aa%5Ccdot%20b%3D40%5Cimplies%20b%3D%5Cfrac%7B40%7D%7Ba%7D%5C%5C%0Athen%5C%5C%0A------------%5C%5C%0Aa%2B%5Cboxed%7Bb%7D%3D-13%5Cimplies%20a%2B%5Cboxed%7B%5Cfrac%7B40%7D%7Ba%7D%7D%3D-13%0A%5Cend%7Bcases%7D)
solve for "a",
what is "b"? well, b = 40/a :)
