Answer:
12x -11
Step-by-step explanation:
Lets start by applying the 2/3 to the two values in the parenthesis. Doing so will yield: 4x -7 +8x -4. We can simplify this to be 12x -11
To get 3 5/6 - 4 5/12, you would have to get the denominators even. So 12 is the lowest, so lets use that.
3 5/6 - 4 5/12
3 10/12 - 4 5/12
3-4= -1
10-5= 5
Now, you have a -1 and a + 5/12, to do this you have to turn -1 into -12/12
-12/12 + 5/12 = -7/12
Your answer is -7/12
