As I understand the equation you are to solve, it is:
.

.
One thing to note in passing is that y cannot be because that would give you
a denominator of zero and division by 0 is not allowed.
.
Let's get rid of the denominator by multiplying both sides by (3y + 1). When you do that
the denominator on the right side cancels with this multiplier and the equation becomes:
.

.
Multiply out the left side and the equation becomes:
.

.
Subtract 3y^2 from both sides and you are left with:
.

.
That's the solution to the problem. You can check by going back to the original problem
and substituting 0 for y and you will find that the equation reduces to 0 = 0/1 which is 0 = 0.
.
Hope this helps.
