Work Step by Step

This question is fairly broad and thus has many possible answers. Here is an example: So far in this course, we learned how to use variables as place holders in equations to solve for desired values. After learning how to do this, we found numerous different ways to solve the equations that we made. For instance, we learned how to use the distributive property, exponents, factoring, and common denominators in order to solve. In addition, we learned how to use strategic variable naming in order to solve problems. After all, sometimes it is easier to solve using certain variables than it is to solve using other variables or assigned values.
