#v = 3#

Step 1 - Expand the terms in parenthesis:

#81 = 3v - 36 + 36v#

Step 2 - Combine like terms on each side of the equation (in this case the right side only):

#81 = 3v + 36v - 36#

#81 = 39v - 36#

Step 3 - Solve for #v# while keeping the equation balanced:

#81 + 36 = 39v - 36 + 36#

#117 = 39v#

#117/39 = (39v)/39#

#v = 3#
