Setup
------
Given: X = 21.5ft / 3
----------------------
Solution
----------------------
I think that it is easier if you convert the feet to inches.
1ft = 12in
So 21.5ft+%2A+%2812in%2F1ft%29+=+258in
Now replace the 21.5ft in the given equation with 258in
X+=+21.5ft+%2F+3
X+=+258in+%2F+3 Simplify
X+=+86in
or you can convert the 86in back into feet if you want.
X+=+86in+%2A+%281ft%2F12in%29
X+=+7.16667ft
