Question
solve each system of equation by substitution. clearly identify your solution.
## Problem 9: Solving a System of Linear Equations You are given a system of linear equations as follows: ### Equations: 1. \( x - y = -9 \) 2. \( 8x - 3y = -62 \) ### Instructions: To solve this system, you can use methods such as substitution, elimination, or matrix operations. Analyze the equations to find the values of \( x \) and \( y \) that satisfy both equations simultaneously. ### Steps: - **Substitution Method**: Solve one equation for one variable and substitute into the other equation. - **Elimination Method**: Add or subtract equations to eliminate one variable, making it easier to solve for the other. - **Matrix Method**: Write the system in matrix form and use row operations to solve. This exercise will enhance your understanding of solving systems of equations, a foundational concept in algebra. ### Graph/Diagram Explanation: There are no graphs or diagrams associated with this problem.
