Well it depends what 'v' stands for

well all you need to do is replace the v with the number it stands for. For example if v=2 then the expression would be 4.2(2) - 5 - 6.5(2)
Then you use the order of operations. first you multiply

8.4 - 5 - 13

then you subtract from left to right 

8.4 - 5 = 3.4

3.4 - 13 =  -13 - 3.4 = -9.4

So IF v=2 (I used 2 as an example, V might not = 2 in your case) then the
answer will be -9.4  

I hope this helped you :3
