You surely mean 6^(x-y) = 4, otherwise it would be trivial.
6^(x-y) = 4
6^x / 6^y = 4
6^y = 6^x/4
y log6 = log(6^x/4)
y = log(6^x/4)/log6
or, if you like,
y = (x log6 - log4)/log6
6^(x-y) = 4
6^x / 6^y = 4
6^y = 6^x/4
y log6 = log(6^x/4)
y = log(6^x/4)/log6
or, if you like,
y = (x log6 - log4)/log6
