Look at the graph of the system of equations: 5x-3y= -3 and x + 3y =21
How can you prove that the point of intersection of the lines on the graph is the solution to both equations?

A. Substitute 6 as the x value in each of the equations and solve for y.
B. Substitute 7 as the y value in each of the equations and solve for x
C. Substitute 3 as the x value in each of the equations and solve for y.
D. Substitute 1 as the y value in each of the equations and solve for x.
