Algebraic Equations with Multiplication and Division
Watch these videos for a few examples of how to solve algebraic equations involving multiplication and division. Pay attention to the problem-solving steps for fractional coefficients in the third video. Instead of dividing both sides by the fraction, you can multiply both sides of the equation by the reciprocal of the fraction. It is often easier to multiply fractions rather than dividing them, so this trick can be useful.
