Systems of Equations |

Two or more equations put together are called Systems of Equations. |
Below, we have a system of equations:
4x + y = 8
3x + 2y = 6
Equations can be multiplied by a constant to allow for elimination by addition or subtraction. This process is called Elimination by Multiplication.

We multiply the first equation by "2" to prepare it for elimination by subtraction.

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

Our solution is (2, 0).
