Solving Linear Equations in Real-Life Scenarios

The video tutorial covers solving word problems using linear equations. It begins with an introduction to the objectives and then walks through two specific problems: one involving river water levels and another about the number of customers styled by a hair expert. The teacher explains how to identify the slope and y-intercept, solve equations, and apply these concepts to real-world scenarios. The session concludes with key takeaways and a homework assignment.

What is the initial water level of the river in the first example?

• 32 feet

• 28 feet

• 30 feet

• 34 feet
