The graph of the two equations :
y = x + 6
y = 2x + 2
is shown clearly.
The solution of the system of equation on a graph is the point where the lines meet each other or interesct each other
In the given graph the intersecting points are :
As the graph cut each other at (4, 10)
So, x = 4 & y = 10 are the solution of the given system of equation
(x, y) = (4, 10)
Solution of the system is x = 4 & y = 10
