You forgot to add the dashes to make it into a fraction, that's why TaskMaster got it wrong. The answer is x=4, for anyone who is on K12 and is taking the quiz. This is because -1/2*6/1 (we got 6/1 by doing 4+2, after replacing all x with 4) equals -6/2 which turns into -3. 3/2 (1 1/2 turned into an improper fraction) times 4/1 equals 12/2, which turns into 6. -3+6 equals 3! Hope this helps <3
