Which equation represents a valid first step to solving the following system of equations using the elimination method if our next step is to add the equations together to eliminate the x variable? 2x - 2y = 5 and -4x + 5y = 11 2(-4x + 5y) = 2(11) -2(2x - 2y) = -2(5) -2(-4x + 5y) = -2(11) 2(2x - 2y) = 2(5)
