and 
Step-by-step explanation:
Let
x and y -----> the numbers
we know that
----->
------> equation A
----> equation B
substitute equation A in equation B and solve for x

Solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to

in this problem we have
so

substitute


Remember that



Simplify



we have two solutions
<u><em>Find the value of y for the first solution</em></u>
For 

substitute


<u><em>Find the value of y for the second solution</em></u>
For 

substitute


therefore
The numbers are
