Make sure you simplify each expression within parentheses first! Then you can multiply from left to right before finally subtracting.
Here, you should simplify the denominator (the bottom expression) before dividing.
Remember to multiply before subtracting! Also, don't forget that multiplying a negative integer and a positive integer is like removing groups of the same number.
