I have a log question and was wondering which is the correct way to find the value of;

-x being part of the exponent.

log 4^3 - x = log 7

I thought I could find the value of -x this way;

log4^3-x = log7

bring down the -x

xlog64 = log7

divide both sides by log64

x = log7 divided by log64

x = 0.47

Is this permissible?

Thanks
