I was doing okay about these until this one!

log6(2x-6) = 2

that first six is a sub...whateveryoucallit.

the 2x-6 part is throwing me off. Help?

Just do it like you normally would.

$log_{6} (2x - 6) = 2$

$(2x - 6) = 6^2 = 36$

$2x - 6 = 36$

$2x = 42$

$x = 21$

3. ah okay i see! Thanks a lot.
