Hey there! :) 

v - 10 = 9

We're very simply just trying to isolate "v."

So, we must get "v" onto its own side of the equal sign.

To do this, we can very easily add 10 to both sides. 

v = 9 + 10 

Simplify.

v = 19

Now, to check our work, all we need to do is plug in "19" for v into our original expression.

v - 10 = 9

(19) - 10 = 9

9 = 9 

Therefore, v = 19

~Hope I helped!~
