i have a quesion(obviously huh?)well it goes like this:

1/3h-4=1/2(4h=8) i sort of unerstand this but i dont know how do to the fraction part.

also theres this one that i think i did right but im not sure

What does (4h=8) means, if it's not typo.

Second one is

-9k = 3k-21+3
-9k-3k =-18
-12k=-18
k=3/2

I find the answer to be k = 3/2, perhaps you can show your work?

Unfortunately, the question isn't clear. What's the "(4h=8)" doing there? And the fractions aren't clear either: try to write it by using brackets.
