Solving Linear Equations with Fractions

The video tutorial reviews solving equations, focusing on the challenges students face with fractions. The teacher introduces a method to eliminate fractions by using the least common denominator (LCD). By applying the LCD, the fractions are simplified, making the equation easier to solve. The tutorial demonstrates the process step-by-step, ensuring students understand how to handle equations involving fractions.
