Determine the solution and the reasoning that justifies the solution to the systems of equations. (4 points)
O (2,7), because this point is true for both the equations
O (4.-6), because this point lles only on one of the two lines
O (4.-6), because this point makes both the equations true
O (2,7), because the lines intersect the x-axis at these points
