Step-by-step explanation:
Collapse the logarithms into one:
Then write both sides as powers of 3:
Simplify the left side and solve for 
:
But we're not done yet. Notice that both 
and 
are negative when 
. We can't take the logarithm of a negative number (the result isn't real-valued, anyway), so we throw this solution out, and we're left with just
Answer:
x=4 y=3
