Exploring Systems of Equations in Word Problems

This video tutorial covers solving word problems using systems of equations. It begins with an introduction to the concept, followed by two examples: one involving running distances and another about mulch delivery costs. The tutorial demonstrates how to set up and solve systems of equations using substitution, providing clear explanations and solutions.
