Linear Equations: Solving More Complex Equations
Now that you can solve simple equations that have just one operation, the next goal is to learn how to solve more complex equations. These new equations contain two or more of the basic operations (addition, subtraction, multiplication, and division). You solve them using more than one of the previous hour’s four properties of equality in a logical order. The challenge comes in knowing which property to use and when to use it. Before the end of this hour, you will be able to rearrange any linear equation’s terms to isolate the variable—in other words, to solve the equation.
