Answer:
The x-coordinate gives the solution of the original equation.
Step-by-step explanation:
Let us assume that the original equation is 2x = x + 5 ........... (1) and the solution that this equation has will be x = 5.
But, if we solve the equation by graphing each side as a separate line i.e. y = 2x and y = x + 5, then solving those two equations we get the solution x = 5 and y = 10.
Therefore, the x-coordinate i.e. x = 5 gives the solution of the original equation (1). (Answer)
