By first expanding the bracket and then rearranging the equation

Explanation:

#-6=3(v+ -3)+12#

First expand the bracket

#-6=3v-9+12#

Second you rearrange the equation to make #v# the subject (remember: when you move a number over to the other side of the equation, you have to change its sign; positive to negative and vice-versa)

#-6-12+9=3v#

This makes

#3v=-9#

Divide both sides by three and you get the answer

#v=-3#
