Find a pair of numbers that have a sum of −3 and a difference of −7.

x = -5 and y = 2

Step-by-step explanation:

You want to start by writing these two equations:

x + y = -3

and

x - y = -7

Then, you want to add the solutions to these two equations, like so:

-3 + -7 = -10

Then, to find the x value, because x > y, divide the answer by two:

-10/2 = -5

So, the x value is -5.

With this information, you can figure out that the y value is 2.

Check the

-5 + 2 = -3

-5 - 2 = -7

Hope this helped
