<PRE><B>Question 560460</B>
solve for x: 
log base 3 (7x+4)-log base 3 of 2 = 2logbase3 of X
----
log3(7x+4) - log3(2) = log3(x^2)
-------
log3[(7x+4)/2] = log3(x^2)
------
[(7x+4)/2] = x^2
----
2x^2 - 7x - 2 = 0
---
x = [7 +- sqrt(49-4*2*-2)]/4
-------
x = [7 +- sqrt(49+16)]/4
----
Positive solution:
-----
x = [7 + sqrt(65)]/4
----
x = 3.7656..
