Solving Two-Step Equations with Fractions

This video tutorial demonstrates how to solve a two-step equation with fractions by first clearing the fractions. The process involves identifying the least common denominator (LCD) and using prime factorization to build it. The tutorial explains how to multiply each fraction by the LCD to eliminate fractions, then solve for the variable by isolating it. The video also covers converting an improper fraction to a mixed number and discusses the optional step of building the LCD. The tutorial concludes with a solution that satisfies the given equation.
