Word Problems in Algebra

This video tutorial explains how to write equations from word problems by following three steps: identifying and defining the variable, creating a variable expression, and setting the expression equal to the total given in the problem. The video includes examples such as calculating the cost of necklaces and determining the number of dogs walked in a business scenario. It concludes with a practice problem about car payments and encourages viewers to practice more word problems to improve their skills.
