Consider the sequence of steps to solve the equation: x - 3 3 = x + 3 step 1 ⇒ x - 3 = 3(x + 3) step 2 ⇒ x - 3 = 3x + 9 step 3 ⇒ x = 3x + 12 step 4 ⇒ -2x = 12 step 5 ⇒ x = -6 identify the property of equality which yields step 5. a) division property b) addition property c) subtraction property d) multiplication property
