Answer: [tex]v = 8[/tex]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[tex]12 = 12+ \frac{v-8}{2}[/tex]
Multiply both sides of the equation by 2 to get:
[tex]24 = 24 + v - 8[/tex]
Subtract 8 from 24 to get 16.
[tex]24 = 16 + v[/tex]
Swap sides so that all variable terms are on the left hand side.
[tex]16 + v = 24[/tex]
Subtract 16 from both sides.
[tex]v = 24 - 16[/tex]
Subtract 16 from 24 to get, you guessed it, 8!
