-2v-10+21<2\left(7-v\right)
Use the distributive property to multiply -2 by v+5.
-2v+11<2\left(7-v\right)
Add -10 and 21 to get 11.
-2v+11<14-2v
Use the distributive property to multiply 2 by 7-v.
-2v+11+2v<14
Add 2v to both sides.
11<14
Combine -2v and 2v to get 0.
v\in \mathrm{R}
This is true for any v.
