Solving Systems of Equations

The video tutorial explains solving systems of equations using substitution and elimination methods. It begins with an introduction to the substitution method, demonstrating how to solve for intersection points of a circle and a parabola. The tutorial then transitions to the elimination method, showing how to find intersection points of a hyperbola and an ellipse. The video concludes with a brief promotion of math courses available for further learning.

What is the first step in the substitution method when solving the system of equations given in the video?

• Solve for x in terms of y

• Eliminate x from both equations

• Substitute y in the first equation

• Factor the quadratic equation
