This is a little bit difficult to answer because it isn't entirely clear which terms go together. I will assume that you meant 2 - (x/1) - (x/2), but that may not be correct. If it is, you can combine all three terms by finding a common denominator.
It this case, the common denominator would be 2.
Multiply the first two terms by (2/1) and leave the third term the way it is because its denominator is already 2.
You will have 2(2/2) - (x/1)(2/2) - (x/2)
or (4/2) - (2x/2) - (x/2)
Add the terms on the top, and place them all over the denominator:
(4 - 2x - x)/2
This simplifies to (4 - 3x)/2 or 2 - (3x/2)
If this is not correct, please try to use parentheses, separating the terms, to make the problem clearer.
