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.
