Least value is too vague.
You can have least positive then answer is A.
You can have most negative then C.
Hope this helps.
3(v + 2) + 4 = 13
Mutiply the bracket by 3
(3)(v)= 3v
(3)(2)= 6
3v+6+4= 13
3v+10=13
Move +10 to the other side
Sign changes from +10 to -10
3v+10-10= 13-10
3v= 13-10
3v= 3
divide both sides by 3
3v/3= 3/3
v= 1
Answer : v= 1
I believe it's
- 1 -

Hope I helped! ( Smiles )
