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.
(a) How do we transform System A into System B?
x Equation [A1] Equation [B1]
× Equation [A2]
x Equation [A2] Equation [B2]

x Equation [A1] + Equation [A2]—> Equation [B2]
x Equation [A2] + Equation [A1] Equation [B1]
