Question 43589: I am having trouble when I get to near the bottom of the answer. I will show what I have.
y/ y+7 + 7/y+7 =8 LCD: y+7
y+7 (y/y+7) + y+7 (7/y+7) = y+7 (8)
I cross out the y+7 on the first set which makes it (y)
I cross out the y+7 on the second set which makes it (7)
for the = part, I see that it should be y+56
am I doing it right so far? If so, can you please help me with the rest because I am totaly lost.

y%2F%28y%2B7%29+%2B+7%2F%28y%2B7%29+=+8
%28y%28y%2B7%29%29%2F%28y%2B7%29+%2B+%287%28y%2B7%29%29%2F%28y%2B7%29+=+8%28y%2B7%29
y+%2B+7+=+8y+%2B+56%29
-49+=+7y%29
-7+=+y
Dividing by a zero makes a statement undefined, so there are no solutions.
y%2F%28y%2B7%29+%2B+7%2F%28y%2B7%29+=+8
y%2F%28-7%2B7%29+%2B+7%2F%28-7%2B7%29+=+8
y%2F0+%2B+7%2F0+=+8
