Answer:
v = -6
Explanation:
1. Add the opposite (turn each subtraction sign into an addition sign and change the number in front of the addition sign to a negative or positive depending on what it was originally).
2. Subtract 4v from both sides of the equation.
3. Subtract 36 from both sides of the equation.
4. Divide both sides of the equation by 9.
5. You will be left with v = -6.
