About This Lesson
The term linear means the power of the variables is 1. There are no squares, cubes or any higher powers and no roots or fractional powers.
It is called a linear equation because its graph of its function is a straight line.
In this lesson you will revise simple equations which do not involve a great deal of transposition
Example
What is x if
x+7 = 12
Just by looking at the question you can see that x = 5 will give the correct answer.
In this case the answer is easy, in some cases you will need to do some transposition of terms to work out the answer
This interactive Linear Function Explorer from Math Open Reference will help you test your understanding.
