1%2F%28x%2B4%29+=+6
1%2F6=%28x%2B4%29+
x=1%2F6-4+
x=-23%2F6
then
1%2F%28x%2B8%29=+1%2F%28-23%2F6%2B8%29=+1%2F%28-23%2F6%2B48%2F6%29=1%2F%2825%2F6%29=6%2F25
answer: B) 6%2F25

to show which part of your formula is the numerator and which part is the denominator.


Without it, your formulas are UNREADABLE in this forum.
