Requirements:
Congratulations, you have chosen to do the solve a linear equation mobile project! In a nut shell this is what you are going to do. You are going to make up your own linear equation (and solve it) on a mobile that is balanced (just like your equation). your prioritise are as follows:

1) Write and solve your linear equation correctly showing each step as one piece of your mobile
2) Making your mobile balanced and able to move freely
3) Including a theme from one (or more) of your classes. Sorry, lunch and recess do not count.
4) Making your project pretty

Grading:
If your solution to your equation is wrong, the best you can get is a Partially Proficient.
