The property of equality being demonstrated in Step 1 is the Subtraction Property of Equality. This property states that if you subtract the same amount from both sides of an equation, the two sides remain equal. In this case, you subtracted 4 from both sides of the original equation \(9/2 x + 4 = 30\), resulting in \(9/2 x + 4 - 4 = 30 - 4\).
Which property of equality is shown in the step 1 below for solving the equation that is displayed?
Original Equation: 9/2 x + 4 = 30
Step 1: 9/2 x + 4 - 4 = 30 - 4
