Example 1: Solve the system of equations by elimination
Elimination Method Example
Solution:
In this example we will "cancel out" the y term. To do so, we can add the equations together.
Elimination Method Solution
Now we can find: x = 2
In order to solve for y, take the value for x and substitute it back into either one of the original equations.
Elimination Method Solution
The solution is (x, y) = (2, 1).
