but it is asking to me to substitute the -7/3 in for x in which I did but its wanting a decimal answer for each ( ) I don't know how to put the log base of 3 into my TI 83 calculator to get the correct answer. can you please help me?

okay I got to that point without using the calculator. Now its wanting me to substitute (-7/3) for x.

so log base of 3 (-7/3 -7) - log base of 3 (-7/3) = log base of 3 (4). but it is wanting decimal answers for all the ( ) and that is where I don't know how to but the base in the calculator
