# KS3. y9. Algebra. Graphical Solution to Simultaneous Equations

We previously learned some algebraic methods to solve simultaneous equations. There are some situations where the equations are not solvable, or not easily solvable by algebraic methods. So today we are going to learn how we can solve them using geometric methods.

Geometrically, the solution to a pair of simultaneous equations is the coordinates of the intersection point. Let’s see this in practice with some equations:
