Find the solution $\mathbf{x}_1^{\star}$ to the system $\left(\begin{array}{rr}1 & 2 \\ -3 & -4\end{array}\right)\left(\begin{array}{l}x \\ y\end{array}\right)=\left(\begin{array}{l}1 \\ 0\end{array}\right)$, and the solution $\mathbf{x}_2^{\star}$ to $\left(\begin{array}{rr}1 & 2 \\ -3 & -4\end{array}\right)\left(\begin{array}{l}x \\ y\end{array}\right)=\left(\begin{array}{l}0 \\ 1\end{array}\right)$. Express the solution to $\left(\begin{array}{rr}1 & 2 \\ -3 & -4\end{array}\right)\left(\begin{array}{l}x \\ y\end{array}\right)=\left(\begin{array}{l}1 \\ 4\end{array}\right)$ as a linear combination of $\mathbf{x}_1^{\star}$ and $\mathbf{x}_2^{\star}$.

Key Concepts

Superposition Principle

The superposition principle states that for any linear system, the response (or solution) to a sum of independent inputs is equal to the sum of the responses (solutions) for each individual input. This principle is fundamental in understanding how complex systems behave as it allows one to build the overall solution from simpler, known solutions.

Linear Combination of Solutions

In a linear system, if the system is linear and the coefficient matrix is consistent with the principle of superposition, then the solution for a composite right-hand side can be constructed as a linear combination of the solutions corresponding to simpler right-hand sides. This leverages the linearity property of the system by allowing us to scale and add particular solutions to obtain a new particular solution.

Systems of Linear Equations

A system of linear equations consists of multiple equations with the same set of unknowns, where each equation is a linear combination of those unknowns. The goal is to find values for the unknowns that simultaneously satisfy all the equations, often by methods such as substitution, elimination, or matrix operations.
