Instead of just giving you the answer, I'll tell you how to solve the problem.

To solve this problem, write two equations. Let one variable be x and the other y. Then you can say:

xy = 800

x + y = -70

Isolate x + y = -70 for y and you get y = -70-x

Then plug it back into the first equation, solve for x and plug your answer into the second equation to solve for y.

Hope that helps, and let me know if you have any questions :)
