The correct answer is 17. Jay forgot to do the multiplication first before he did addition inside the parenthenses. This is why he should have looked carefully.

3x (3+12:3) - 4, your first step would be to distribute. 9x+36x:9x-4, you will then have to collect like terms and get 13x-4 as the answer. Jay got it wrong because instead of distributing like he is suppose to he divided what was on the inside of the parenthesis and then added it together
