Geometry and Algebra Problem Solving

This video tutorial covers a live session where the instructor solves four math problems: a perimeter word problem, a graphing inequalities problem, a system of equations, and a ratios word problem. The session includes detailed explanations and step-by-step solutions, emphasizing key concepts and methods such as the elimination method for systems of equations. The instructor also provides tips for solving these types of problems on the TEAS test and offers resources for further learning. The session concludes with a giveaway announcement.
