Intersection points of graphs & equations

In this video you will learn how to calculate the x-coordinate and y-coordinate of the intersection point of a graph. When you have calculated the x-coordinate and y-coordinate, you can give the coordinate of the intersection point. Because a coordinate has an x-value and a y-value. Think about S(x, y) 

Equations with brackets

In this video you will learn how to solve linear equations when you have to multiply out of brackets first.
