Solving matrix problems involves various operations such as addition, subtraction, multiplication, finding determinants, inverses, and solving systems of linear equations. Here is a general guide to solving matrix problems:

1. Matrix Addition and Subtraction:

   • Ensure the matrices have the same dimensions.
   • Add or subtract corresponding elements.

2. Matrix Multiplication:

   • Check if the number of columns in the first matrix equals the number of rows in the second matrix.
   • Multiply corresponding elements and sum them up.

3. Finding the Determinant:

   • For a 2x2 matrix $\begin{bmatrix}a & b \\ c & d\end{bmatrix}$, the determinant is $ad - bc$.
   • For larger matrices, use cofactor expansion or row reduction methods.

4. Finding the Inverse:

   • For a 2x2 matrix $\begin{bmatrix}a & b \\ c & d\end{bmatrix}$, the inverse is $\frac{1}{ad - bc} \begin{bmatrix}d & -b \\ -c & a\end{bmatrix}$, provided $ad - bc \neq 0$.
   • For larger matrices, use the Gauss-Jordan elimination method or the adjugate method.

5. Solving Systems of Linear Equations:

   • Represent the system as a matrix equation $AX = B$.
   • Use the inverse of matrix $A$ to find $X = A^{-1}B$, or use methods like Gaussian elimination.
