Two systems of equations are given below. For each system, choose the best description of its solution. If applicable, give the solution O The system has no solution. O The system has a unique solution: System A X (x , y) - ID x- 3y=-6 -x+3y-6=0 O The system has infinitely many solutions. They must satisfy the following equation: O The system has no solution O The system has a unique solution: System B (x , y) = (ID) -x+3y=-9 O The system has infinitely many solutions. x - 3y=-9 They must satisfy the following equation: y=
