Learn how to solve a rational equation when the solution does not work when plugged in

The video tutorial explains the difference between combining and solving equations, emphasizing the importance of using the Least Common Denominator (LCD) to eliminate fractions rather than combining them. The instructor demonstrates how to solve an equation by multiplying through by the LCD, leading to a simplified equation without fractions. The tutorial also highlights the importance of understanding constraints and recognizing when an equation has no solution due to these constraints.

Why is it important to remember the constraints on the variable when solving equations?
