The video tutorial explains how to solve equations involving matrices. It begins with an introduction to matrix equations, highlighting the differences from regular equations. The tutorial then demonstrates solving for matrix X by subtracting matrices to isolate X. It emphasizes careful handling of integer operations, especially with negatives. The tutorial proceeds to solve for matrix Z by adding matrices to both sides and then dividing by a scalar. The process involves combining matrices and simplifying to isolate Z, ensuring a clear understanding of matrix operations.
