Answer:

-50 and -60

Explanation:

Let the two numbers be x and y. We know:

x + y = -110

We also know one number is 10 less than the other:

x = y - 10

We can use systems of equations via substitution method to help.

(y-10) + y = -110

Add like terms:

2y - 10 = -110

Add 10 on both sides.

2y = -100

Divide by 2.

y = -50

Now, find x by plugging this value of y into one of the equations.

x + (-50) = -110

so.. x = -60
