Solving a System of a Quadratic and Linear Equation by Substitution

In this video, the teacher explains how to solve a system of a quadratic and linear equation using substitution. They review the concept of a system of equations and the process of substitution. The teacher then guides the viewers through an example, demonstrating how to substitute the quadratic equation into the linear equation and solve for the variables. The lesson concludes by discussing the significance of finding both the X and Y values and interpreting the solutions as imaginary in this particular case.
