The answer in terms of y and x is
\(y < -(2x^2 - x + 6)/(x^2) - 3\).

Step 1: Find a common denominator

The common denominator is
\((2x^2 - 2x)(2x^2 + 4)\):


\[((y + 3)(2x^2 + 4))/((2x^2 - 2x)(2x^2 + 4)) < (-1(2x^2 - 2x))/((2x^2 - 2x)(2x^2 + 4))\]

Step 2: Distribute and simplify

Expand both the numerator and denominator:


\[(y + 3)(2x^2 + 4) < -1(2x^2 - 2x)\]

Step 3: Isolate y

Distribute and combine like terms:


\[2x^2y + 4y + 6x^2 + 12 < -2x^2 + 2x\]

Subtract
\(-2x^2 + 2x\) from both sides:


\[2x^2y + 4y + 6x^2 + 12 + 2x^2 - 2x < 0\]

Combine like terms:


\[2x^2y + 6x^2 + 4y - 2x + 12 < 0\]

Step 4: Express the solution for y in terms of x

Factor out
\(2x^2\) from the terms with
\(x^2\) and factor out 2 from the terms with y:


\[2x^2(y + 3) + 2(2x^2 - x + 6) < 0\]

Divide both sides by 2 to simplify:


\[x^2(y + 3) + 2x^2 - x + 6 < 0\]

Now, you have the solution expressed for y in terms of x:


\[y + 3 < -(2x^2 - x + 6)/(x^2)\]

So, the answer in terms of y and x is
\(y < -(2x^2 - x + 6)/(x^2) - 3\).



The probable question can be:

Question:

Solve the inequality
\((y + 3)/(2x^2 - 2x) < (-1)/(2x^2 + 4)\). Which of the following expressions represents the solution for \(y\) in terms of \(x\)?

a.
\(y > -(2x^2 - 2x + 4)/(2x^2 + 4)\)

b.
\(y < (2x^2 - 2x - 4)/(2x^2 + 4)\)

c.
\(y > (2x^2 + 2x - 4)/(2x^2 + 4)\)

d.
\(y < -(2x^2 + 2x + 4)/(2x^2 + 4)\)
