x and y, the numbers.
y=3%2B2x
and you want xy=-1.

x%282x%2B3%29=-1
2x%5E2%2B3x%2B1=0
%282x%2B1%29%28x%2B1%29=0

Either x=-1/2 or x=-1.

If x=-1%2F2
y=3%2B2%28-1%2F2%29
y=1

If x=-1
y=3%2B2%28-1%29
y=1

---------------------------------------
SUMMARY
The two solutions are :
Numbers are -1/2 and 1
or
Numbers are -1 and 1.
