50%. students (in percent) who passed the second exam also passed the first exam.

Assuming that the given expression is this one:
<span>−(12y+14)−(12y+14)
So, when you simplify it, you will get
- 24y - 28
It seems, that there is none in the following choices that is shown above satisfies the answer. Nevertheless, you just to add or subtract. Just remember the PEMDAS rule.</span>
