Kasey is thinking of 2 munbers. The sum of the two numbers is -18. Their difference is 38. Write a system of equations that can be used to find the numbers.

Eq1: X + y = -18.

Eq2: X - Y = 38.

Well, isn't Kasey just a real math whiz!

Let's call the two numbers Kasey is thinking of, "x" and "y."

We know that the sum of the two numbers is -18, so our first equation is:

x + y = -18

And we also know that their difference is 38, so our second equation is:

x - y = 38

Now you have a system of equations to solve. Good luck, mathlete!

To find the system of equations, let's denote the two numbers as x and y.

According to the given information, we can establish the following equations:

1) The sum of the two numbers is -18:
x + y = -18

2) The difference between the two numbers is 38:
x - y = 38

Thus, the system of equations is:
{
x + y = -18,
x - y = 38
}

To write a system of equations, let's denote the two unknown numbers as x and y. We can then translate the given information into equations.

1. The sum of the two numbers is -18:
x + y = -18

2. The difference between the two numbers is 38:
x - y = 38

So, the system of equations representing the problem is:

x + y = -18
x - y = 38

By solving this system of equations, we can find the values of x and y.
