1. **State the problem:** Solve the system of equations using the elimination method:
$$2x + 5y = 9$$
$$2x + 3y = 7$$
2. **Explain the elimination method:** The goal is to eliminate one variable by subtracting or adding the equations so that one variable cancels out.
3. **Subtract the second equation from the first:**
$$\begin{aligned}
(2x + 5y) - (2x + 3y) &= 9 - 7 \\
2x - 2x + 5y - 3y &= 2 \\
0 + 2y &= 2 \\
2y &= 2
\end{aligned}$$
4. **Solve for $y$:**
$$y = \frac{2}{2} = 1$$
5. **Substitute $y=1$ into one of the original equations to find $x$:** Using the second equation:
$$2x + 3(1) = 7$$
$$2x + 3 = 7$$
$$2x = 7 - 3 = 4$$
6. **Solve for $x$:**
$$x = \frac{4}{2} = 2$$
7. **Final answer:**
$$\boxed{x=2, y=1}$$
