"a facton of third over four" ??? That is a rather odd way to describe the fraction -- if that is what you really meant.
If
is what you were trying to represent, then the correct way to do it so that there would be no guesswork would have been to write:
1 - (3/4)(v+2) = -5
Perform the following steps to solve for , which is what I am guessing you want. I'm guessing because you didn't bother to say what it was that you wanted.
