Homework Help: Math

Find X

27^4x-2=243^3x=6

Please Explain

Thanks

Is this a repeat of the problem you posted earlier? If so, it should be
274x-2 = 2433x+6
You might try it the hard way.
(4x-2)*log 27 = (3x+6)*log (243)
Solve for x. I get -12.
Post your work if you get stuck.


You have too many = signs. Is the second one (before the 6) supposed to be a + or - ? Is the first exponent supposed to be x-2 or x ?

You need to learn how to use parentheses to clarify your equations when typing them.
