By inspection, you should be able to determine that the only value at which they are equal is zero,.

Take its log(12),then you'll have:
x = 3x log(12) 14.
Look up log(12) 14 in a table of numbers and such. After that x would be left the only thing you don't know.

I would say :
12^x=14^3x , so we take logarithm for both sides
log(12^x) = log(14^3x) , now we use logarithmic relations log(a^b)=b*log(a) so we have:
x*log12 = 3x*log14 but we will leave our 3 in logarithm so:
x*log12 = x*log(14^3) -> x*log12 = x*log2744
so we can resolve it only when x=0
... i think :)
