1. **State the problem:** Determine the type of system and the number of solutions for the system of equations:
$$2x + 3y = 9$$
$$6y = 4x - 6$$
2. **Rewrite the second equation in standard form:**
$$6y = 4x - 6 \implies 4x - 6y = 6$$
3. **Compare the two equations:**
Equation 1: $$2x + 3y = 9$$
Equation 2: $$4x - 6y = 6$$
4. **Check if the system is consistent and determine the number of solutions by comparing ratios of coefficients:**
Calculate the ratios:
$$\frac{a_1}{a_2} = \frac{2}{4} = \frac{1}{2}$$
$$\frac{b_1}{b_2} = \frac{3}{-6} = -\frac{1}{2}$$
$$\frac{c_1}{c_2} = \frac{9}{6} = \frac{3}{2}$$
5. **Interpretation:**
Since $$\frac{a_1}{a_2} \neq \frac{b_1}{b_2}$$, the lines are not parallel.
Therefore, the system has **one unique solution**.
6. **Find the solution:**
From equation 1:
$$2x + 3y = 9 \implies 2x = 9 - 3y \implies x = \frac{9 - 3y}{2}$$
Substitute into equation 2:
$$6y = 4x - 6$$
$$6y = 4 \times \frac{9 - 3y}{2} - 6$$
Simplify:
$$6y = 2(9 - 3y) - 6 = 18 - 6y - 6 = 12 - 6y$$
Add $$6y$$ to both sides:
$$6y + 6y = 12$$
$$12y = 12$$
Divide both sides by 12:
$$\cancel{12}y = \frac{12}{\cancel{12}} \implies y = 1$$
Substitute $$y=1$$ back into $$x = \frac{9 - 3y}{2}$$:
$$x = \frac{9 - 3(1)}{2} = \frac{9 - 3}{2} = \frac{6}{2} = 3$$
**Final answer:** The system has one unique solution at $$\boxed{(3,1)}$$.
