Master Solving Linear Systems Using Substitution: 3 Complete Examples Explained!
In this video, we’ll explore how to solve linear systems of equations using the substitution method. We’ll work through 3 complete examples, providing a step-by-step outline of the basic idea. We’ll focus on systems involving two equations and two unknowns, demonstrating how substitution can simplify the process. At the beginning, we’ll also review quick graphs illustrating the types of solutions a linear system can produce: zero solutions, one solution, or infinitely many solutions.
