A student solves the following problem: Problem: 2(x − 3) + 3x = 19 Step 1: 2a-6 + 3x = 19 Step 2: 6x6 = 19 Step 3: 6a-6 + 6 = 19 + 6 Step 4: 6x 6x Step5: 뜸 = 25 || = Step 6: 4.17 Where is the mistake? What did the student do incorrectly? Step 3: Student should have subtracted 6 from both sides, not added 6. Step 2: Student should have added 2x + 3x = 5x, not 2 x 3 = 6x Step 1: Student should have only distributed the 2 to the x and not the x & 3. O Step 5: Student should have subtracted 6 from both sides, not divided by 6
