Expression and Equation

This is a continuation about algebra. We have covered definitions of the various terms used in algebra such as variables, like terms etc. We discussed about fundamental concepts and differences between expressions and equations.

Task 1:
In this task review the view clip again on how ' x finds out his value'.

Go through the site Study Guides and Strategies and attempt the following questions.

What is the difference between an equation and an expression?
What are the characteristics of a linear expression?
What does it mean to solve an equation?
Can an equation have multiple solutions?
Task 2:
Solve the following equations for the value/s of x.

1. 8x - 46 = 2
2. 8x + 46 = 2
3. -8x +46 = 2
4. 8x + 46 = 46
5. 8x + 46 = 8x

What is the significance of the solutions of the above equations? (are there one, many or no solution?)
Can an equation have multiple solutions or no solution? If so, what is the implication.
