![### Solving a System of Linear Equations: Elimination Method
**Topic: Linear Systems**
**Objective:** Solve a system of linear equations using the elimination method.
---
**Problem:**
Solve the following system of equations:
\[
\begin{align*}
9x + 6y &= -3 \\
5x + 6y &= 9
\end{align*}
\]
**Solution Process:**
1. **Identify the Equations:**
- Equation 1: \(9x + 6y = -3\)
- Equation 2: \(5x + 6y = 9\)
2. **Elimination Method:**
- Subtract Equation 2 from Equation 1 to eliminate \(y\).
3. **Solve for Variables:**
- Calculate the value of \(x\).
- Substitute the value of \(x\) back into one of the original equations to find the value of \(y\).
---
**Input Fields:**
- \( x = \) (Blank input field)
- \( y = \) (Blank input field)
**User Interface Controls:**
- A series of icons for performing operations such as:
- Subtraction (depicted by a subtraction icon)
- Reset (depicted by a reset arrow icon)
- Help (depicted by a question mark icon)
**Bottom Navigation:**
- Explanation Button (Provides detailed step-by-step solution)
- Check Button (Submits the answer for validation)
---
By following these steps, you should be able to solve systems of linear equations using the elimination method efficiently.
