Lisa wrote the expression (3 + 6x) – 2(x + 1) + 5. She simplified the expression using the following steps: Step 1: 3(1 + x) – 2(x + 1) + 5 Step 2: 3(x + 1) – 2(x + 1) + 5 Step 3: (x + 1) + 5 Step 4: x + 6 Lisa says that (3 + 6x) – 2(x + 1) + 5 = x + 6. Lisa's statement is incorrect. In which step did Lisa first make a mistake, and what is a correct expression for that step? @ Step 1; 3(1 + 3x) – 2(x + 1) + 5 © Step 1; 3(1 + 2x) – 2(x + 1) + 5 © Step 3; 5(x + 1) + 5 © Step 3; 6(x + 1) + 5
