²log x = p
³log (x + y) = q

p + q = 5
p - q  = 1
------------- +
    2p = 6
      p = 3

p + q = 5
3 + q = 5
q = 5 - 3
q = 2

³log (x + y) = q
x + y = 3²
x + y = 9

²log x = p
³log (x + y) = q

p + q = 5
p - q  = 1
------------- +
    2p = 6
      p = 3
3 + q = 5
q = 5 - 3
q = 2

³log (x + y) = q
x + y = 3²
= 3×3
= 9
