4. ok here it goes:

h= d/3+2

To get your variable "D" alone cancel out the "/3" by multiplying both sides by 3

3h= D + 2

Now all you need to do is minus two from both sides, to get rid of the "2" next to the desired variable "D". This gives you "D" as your subject

3h-2=D
5. its actually 3h-6=d

because u have to get rid of the denominator by multiplying by 3 meaning the +2 also gets multiplied by 3,

so u have 3h=d+6

then 3h-6=d
