since no base is stated, assume base 10
remember
loga-logb=log(a/b)
also

log_a(b)=c translates to
a^c=b
and log(a^z)=zlog(a)

log25x-log5=2 means

log_(10)(25x)-log_(10)(5)=2 translates to

log_(10)( (25x)/(5) )=2 simplies to

log_(10)(5x)=2 translates to

10^2=5x expands to
100=5x
divide both sides by 5
20=x
