The key to solving long equations like this is PEMDAS: Parentheses Exponents Multiplication Division Addition Subtraction. Thus, the first stuff to do is inside the parentheses, and within those the multiplication goes before the division. So, the 3 times 2 becomes 6, within the parentheses you have 14 - 6 or 8, then the division–8 divided by 4–and then add and subtract left to right. You get -2.
