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
