Let's satrt by copying the equation:
Firslty, let's leave the equation with all the terms with v on one side and all the term without v on the other.
The right side has all the terms with v, but there is one without v that we need to pass to the other side., we can do that by substracting both sides by 27:
Now, we evaluate the like-terms on each side:
Now, we can invert the sign so that the variable v go to the left side, as usual:
To finish the solve. we can divide both sides by 9:
