Matharena - Linear Equations

*Performance and lyrics by Vicki Young
Melody: “Macarena” *

We're solving equations; we want to find the answer.

It has to fit just right; that's the number we are after.

At first we'll take our time, but then we'll travel faster!

Do the matharena!

Solving equations, I want to be emphatic!

You must decide: is it linear or quadratic?

Then check your plan - plan to check, while you're at it!

Do the matharena!

What is the plan when “x” is only __first degree?__

__Clear__ - that means distribute - and __collect__ like terms
you see!

Last (but not least) you must __cancel__ so that
“x” is free!

Do the matharena!

What do you do if certain terms just disappear?

There are 3 cases - we need to make them crystal clear!

__One__ solution, __no__ solution, or __any number__
anywhere!

Do the matharena!

As long as an "x" is left in your equation,

You'll have __one__ solution, you'll find it if you're
patient!

That answer will be zero if the number side is vacant!

Do the matharena!

When both sides are zero, your answer's __any number__.

When only letters drop out, what's left may make you wonder:

The answer's __no solution__ - you no longer have
to ponder!

Do the matharena!
