8.EE.3.7 Nicholas showed his friend Alma the problem shown from his homework. He told her that his answer was marked wrong but he could not find his mistake. Alma told him that she found his mistake. What was Nicholas' mistake on the problem? Step 1: 2x – 3(x + 2) = -8 Step 2: 2x 3x + 2 = -8 Step 3: Step 4: Step 5: -x + 2 = -8 -x = -10 x = 10 A) Alma said that there is a distribution error from step 1 to step 2. B) Alma said that there is an addition error from step 2 to step 3. C) Alma said that there is a subtraction error from step 3 to step 4 D) Alma later decided that Nicholas was correct; there were no errors in the solution to the problem.
