Sal has created new algebra videos to explain solving systems of equations:
The King’s planning a party and needs your help figuring out how many cupcakes to order.
Then, the King needs more party planning help in managing The Potato Chip Issue:
Next, a little bird visits the King to teach him a new solving method: substitution.
Solutions to Systems
Sal then investigates special situations you may run into, including systems without a solution:
and systems with infinite solutions:
Our exercise on how many solutions a system of equations has also comes with a new companion video.
