Introduction

---

Algebraic expressions are a fundamental concept in mathematics, and simplifying them is an essential skill for any math enthusiast. In this article, we will explore the process of simplifying algebraic expressions, with a focus on equivalent expressions. We will examine a specific problem, where we need to select the correct answer, which expression is equivalent to $\frac{3}{2}$.

Understanding Equivalent Expressions

---

Equivalent expressions are algebraic expressions that have the same value, but may be written in different forms. To determine if two expressions are equivalent, we need to simplify them and compare their values. In this case, we are given four options, and we need to select the one that is equivalent to $\frac{3}{2}$.

Option A: $\frac{3y}{2y-6}+\frac{9}{2y-6}$

---

Let's start by analyzing Option A. We can simplify this expression by combining the two fractions:

$$\frac{3y}{2y-6}+\frac{9}{2y-6} = \frac{3y+9}{2y-6}$$

However, this expression is not equivalent to $\frac{3}{2}$. To see why, let's try to simplify it further:

$$\frac{3y+9}{2y-6} = \frac{3(y+3)}{2(y-3)}$$

As we can see, this expression is not equivalent to $\frac{3}{2}$.

Option B: $\frac{9}{y}-\frac{6}{y+2}$

---

Now, let's analyze Option B. We can simplify this expression by combining the two fractions:

$$\frac{9}{y}-\frac{6}{y+2} = \frac{9(y+2)-6y}{y(y+2)}$$

Simplifying further, we get:

$$\frac{9(y+2)-6y}{y(y+2)} = \frac{18+18y-6y}{y(y+2)}$$

$$= \frac{18+12y}{y(y+2)}$$

However, this expression is not equivalent to $\frac{3}{2}$. To see why, let's try to simplify it further:

$$\frac{18+12y}{y(y+2)} = \frac{18(1+2y/3)}{y(y+2)}$$

As we can see, this expression is not equivalent to $\frac{3}{2}$.

Option C: $\frac{3y}{2y-6}+\frac{9}{6-2y}$

---

Now, let's analyze Option C. We can simplify this expression by combining the two fractions:

$$\frac{3y}{2y-6}+\frac{9}{6-2y} = \frac{3y(6-2y)+9(2y-6)}{(2y-6)(6-2y)}$$

Simplifying further, we get:

$$\frac{3y(6-2y)+9(2y-6)}{(2y-6)(6-2y)} = \frac{18y-6y^2+18y-54}{(2y-6)(6-2y)}$$

$$= \frac{36y-6y^2-54}{(2y-6)(6-2y)}$$

However, this expression is not equivalent to $\frac{3}{2}$. To see why, let's try to simplify it further:

$$\frac{36y-6y^2-54}{(2y-6)(6-2y)} = \frac{6(6y-y^2-9)}{(2y-6)(6-2y)}$$

As we can see, this expression is not equivalent to $\frac{3}{2}$.

Conclusion

---

After analyzing all four options, we can conclude that none of them are equivalent to $\frac{3}{2}$. However, we can try to simplify the expressions further to see if we can find a common factor.

Simplifying the Expressions

---

Let's go back to Option A and try to simplify it further:

$$\frac{3y+9}{2y-6} = \frac{3(y+3)}{2(y-3)}$$

We can see that the numerator and denominator have a common factor of 3. Let's try to factor it out:

$$\frac{3(y+3)}{2(y-3)} = \frac{3(y+3)}{2(y-3)} \cdot \frac{1}{1}$$

$$= \frac{3(y+3)}{2(y-3)} \cdot \frac{1}{1}$$

However, this expression is still not equivalent to $\frac{3}{2}$.
