Best ResponseYou've already chosen the best response.0The work of a student trying to solve the equation 2(2x − 3) = 6 + 2x + 4 is shown below: Step 1: 2(2x − 3) = 6 + 2x + 4 Step 2: 4x − 3 = 10 + 2x Step 3: 4x − 2x = 10 + 3 Step 4: 2x = 13 Step 5: x = 6.5 In which step did the student first make an error and what is the correct step? Step 2: 4x − 6 = 10 + 2x Step 2: 4x − 3 = 2 + 2x Step 3: 4x + 2x = 10 + 3 Step 3: 4x − 2x = 10  3

Best ResponseYou've already chosen the best response.1he distributed the 2 over the 2x  3 and multiplied 2*2x = 4x that was correct. Then the mistake happened.
