question below

Consider the following three systems of linear equations. System A System B System C 5x +6y = -9 [A1] - 7x - 21 [B1] - -3 [01] -4x -2y = 10 [A2] -4x - 2y = 10 [B2] -4x - 27 = 10 [C2] Answer the questions below. For each, choose the transformation and then fill in the blank with the correct number. The arrow () means the expression on the left becomes the expression on the right. How do we transform System A into System B? O x Equation [A1] - Equation [81] X O x Equation [A2] - Equation [B2] O x Equation [41] - Equation [A2] - + Equation [B2] D x Equation [A2] - Equation [A1| Equation [81] How do we mansform System Bingo System Op x Equation [B1] Equation [(1] x Equation [82] - Equation 102
