Answer:
-7 and 6
Explanation:
You can solve this problem by setting up a system of equations. Lets call the first number x, and the second number y. Now:
x*y=-42
x+y=-1
You can subtract y from both sides of the second equation to get x=-y-1, which you can then substitute into the first:
(-y-1)*y=-42
-y^2-y=-42
y^2+y-42=0
Solving the quadratic equation:
(y-6)(y+7)=0
y=-7 or 6
x= 6 or -7
When one of the numbers is -7, the other is 6, and when it is 6, the other is -7. Hope this helps!
