Solving an equation with multiple fractions

The video tutorial demonstrates how to solve an equation involving fractions by eliminating the fractions through finding a common denominator. The instructor explains the process of multiplying all terms by the least common multiple of the denominators to simplify the equation. The solution is then simplified to its lowest terms, providing a clear understanding of the method to solve such equations.

What is the main challenge when dealing with the equation 2/3 + 3M/5 = 31/15?
