The expression (5x-1)/(x+3) is equivalent to which of the following?  Choose the correct choice from the following:
A) (5-2)/3
B) 5 – (2/3)
C) 5 – (x)/(x+3)
D) 5 – (17)/(x+3)
E) 5 - (16)/(x+3)
Easiest way is to pick any number and put in (5x-1)/(x+3). Then check the options with the same number.   I took x=1 and got 5 - (16)/(x+3) as the answer.
