Answer:

x = 44

Explanation:

You can rewrite logarithm equations like so:


log_(b)(x) = y\\\\x = b^y

A way to remember this is the base in the logarithm is also the base in the exponent - then remember this base b is to the power of what's on the other side - and all this is equal to whatever's in the parentheses.

In this case,


log_3(2x-7) = 4\\2x - 7 = 3^4\\x = (3^4 + 7)/2 = 44
