You can put this solution on YOUR website!
In this problem:
%286x%5E7y%2F7%29%283x%5E3%2F4y%5E2%29
If you notice first you can simplify, there is a y on both sides which one can be subtracted by the other (simplifying):
y%5E2+-+y+=+y
%286x%5E7%2Across%28y%29%2F7%29%283x%5E3%2F4y%29
Next you can simplify the 6 and 4, by dividing them both by 2:
6+%2F+2+=+3
4+%2F+2+=+2
%283x%5E7%2F7%29%283x%5E3%2F2y%29
Now you can multiply across, there isn't more simplifying at this point:
%283x%5E7%29%283x%5E3%29=+9x%5E10
%287%29%282y%29=14y
9x%5E10%2F14
There isn't more simplifying here. Answer.
