I hope the expression is [tex] 3(x+y)-\frac{3}{x-y}+5 [/tex].
Hope this is your question, if not I think you will, still be able to
find an answer of your question based on this solution.
We need to evaluate the above expression for x=4, y=3.
So, first step is to plug in for x=4, y=3 in the above expression. Hence,
[tex] 3(4+3)-\frac{3}{4-3}+5 [/tex]
=[tex] 3(7)-\frac{3}{1}+5 [/tex]
= 21 - 3 + 5
= 26 - 3
= 23
So,A is the correct choice.
