#v = -1#

Explanation:

Original: #" "2+6v = -8-4v#

(add #4v# to both sides) #" "2+10v = -8#

(subtract #2# from both sides) #" "10v = -10#

(divide #10# from both sides) #" " v = -1#

So it may be more helpful if you see something like this and are stuck to imagine the different operations of the equation as individual parts. For example,

#(+2), (+6v) = (-8), (-4v)#

In order to "get rid" of the different separated parts of this equation, just do the opposite operation to the opposite side. For example, to cancel out #(-4v)#, just add #(+4v)# to #(+6v)#. You should end up with the same answer of #-1# after you have divided #-10# by #10#.

#v=-1#

Explanation:

#2+6v=-8-4v#

First begin by adding #8# to each side:

#10+6v=-4v#

Second, subtract #6v# from each side because you want to get the #v# variables on one side of the equation:

#10=-10v#

Lastly, divide each side by #-10# so #v# can be by itself on one side of the equation

#-1 =v#
