so the subject of math will be your top pick
if you don’t get it right away
don’t worry cause you will master it today
(chorus)
Systems of equations, bro!
If you really want to go to college
It would help to know this knowledge
and if you plan to rule the nation
you gotta start by solving the equation
substitution, graphing, and elimination too
you see how easy it is to get in the groove
Take a look at the equation on the screen
It’s there in big font so it can be easily seen
2x + 2y = 6 and that’s no lie
4x - 6y =12, you give it a try
Pick your first equation and move x to the back
and when it looks like this you’re on the right track.
The Next step, is to divide by 2
Keep it going, you got it Boo!
The slope is -1 and the y-intercept is 3
Come along now, and do the next part with me
Follow the same steps on the next one
Don’t give up yet because we’re almost done
If your slope is 2 over 3 and your y-intercept is -2
hang on now, let me show you what to do
now that you’re on the right path
lets go ahead and plot the points on the graph
And BOOM we are finished
Your stress should be diminished
But you know what’s neat?
the solution, is the line where they meet!

substiutuion graphing and elimination too
you see how easy it it is to get in the groove
Alright now lets do substitution
I will teach it faster than you can say the constitution
this one is a little different than the last one
but that is a- okay because u can do it hun
we are starting with 3y - 2x = 11 & y + 2x = 9
that sounded like a lot
but trust me you will do just fine
since you already know what y is
plug it in the other problem,
like a math whiz

substiutuion graphing and elimination too
you see how easy it it is to get in the groove
solve for “x”using distrubtive property
you know how to do that, right?
combine like terms and divide by -8
knowing you found “x” will help me
sleep better at night!
place this new x into the other equation
to solve for y
if you if you divided by 2 and subtracted 4 to get 5
your the smart kid I want to stand by!
First you solve for x, then for y
Next thing you know you’re flying high
