What is the answer to v-10=9

Hi Barrows!

First to add 10 from both sides!

v-10=9
  +10 +10

Then crossout of negative 10 and positive 10 too.

Answer is v=19

Answer 2

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
