Solving Equations Using Division and Multiplication The Golden Rule of Algebra almost always* applies when multiplying or dividing both sides of the equation by the same thing. *almost always applies …

Solve Using Multiplication Our goal is (once again) to get the variable all by itself. We are going to take advantage of our multiplicative identity property. (Which is……)

Solve Using Division Once again, we are going to take advantage of multiplicative identity.

Sometimes, we multiply or divide by a negative number
