Perform the same operations to both sides of the equation to isolate #v# and find that

#v = 9#

#3v-12=15#

Isolate the term including #v# by adding #12#:

#3v - 12 + 12 = 15 + 12#

#3v = 27#

Change the coefficient of #v# to #1# by dividing by #3#:

#(3v)/3 = 27/3#

#v = 9#

Finally, check the result:

#3(9)-12 = 27 - 12 = 15#

as desired.
