Quizplus · Accepted Answer

To determine if the ordered pair (4,3) is a solution, substitute x=4 and y=3 into both equations. For the first equation, y = -x - 1 becomes 3 = -(4) - 1, which simplifies to 3 = -5, which is false. Therefore, the ordered pair (4,3) does not satisfy the system of equations.
