Systems of Equations |
---|
Two or more equations put together are called Systems of Equations. |
Below, we have a system of equations:
4x + 2y = 8
3x + 2y = 6
Sometimes, subtracting one equation from the other will allow you to remove a variable, and then solve for the remaining variable. This is called Elimination by Subtraction.

Now that we know "x", we can use this information to solve for "y".

Our solution is (2, 0).
