Put this value in for the second equation for x
General steps are in bold.
Explanation:
Make two equations. Let
First equation: The sum of two numbers adds up to
Second equation: The difference between the two numbers is
Now you can solve for one of the variables by taking either equation. I will use the first equation to solve for
Since you now know what
sub in
Now you have the
sub in
Therefore the two numbers are
