Students do a song and dance in a classroom about solving equations with addition and subtraction. It was created for an algebra class. (Run time 2:54)
These are some of the lyrics for the song:
Alright we gonna do the basic steps
You must isolate...
The Variable
From the rest
Of the equation
Then use
Inverse operations
Lets subtract now first
X 5
Equals -13...
So whats x equal?
Well you add 5
To both sides
Which makes it
-8.
Addition now!
Well its real similar...
To subtracting it
But instead
It has a twist
Instead of subtracting.
You do some adding! You do some adding!
Okay lets take
3 + X
and that equals
a positive 5
Now to solve
What X equals
You must subtract
3 from each side
and that equals 2!
