How can you determine if a point is a solution to a system of equations?

Back

Substitute the point's coordinates into both equations; if both equations are satisfied, it is a solution.

Front

What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other.
