Answer: The two numbers are 1 and 9.
Answer: 9 and 16
Step-by-step explanation:
Say one of the numbers is x and the other is y.
Set up a system of equations:
Move around the first equation so that you can plug it in to the second equation.
Plug it into the second equation.
Solve it out.
Use the quadratic formula to solve for y.
Now plug it in and test out the values of each.
Let's do the first one first.
Wow! We can see that it is equal to the 2nd y value we produced.
But let's double check.
We are correct. The order of x and y doesn't matter because we can see that the two numbers are 9 and 16. Hope that helps.
