Solving Equations with Reciprocals

This video tutorial explains how to solve equations with fractional coefficients using two methods. The first method involves multiplying both sides by the denominator, while the second method uses the reciprocal of the coefficient. Both methods yield the same result, but the reciprocal method is slightly more efficient. The video compares these methods and provides a step-by-step guide to solving such equations.
