- How do you solve -3x = 27?
- How do you get x by itself in an equation?
- How do you solve an equation where you have to combine like terms first?
This video continues where part 1 leaves off. You will learn how to multiply or divide both sides of the equal sign of a basic equation using properties of equality in order to get the variable by itself. This time, you need to use what was learned in part 1 and add a new technique.
