Answer:
v = -16
Explanation:
Move the variable to the left-hand side and change its sign, so it would then be -28 - v = -12
Then move the constant to the right-hand side and change its sign, so it would become - v = -12 + 28
Then you would calculate the sum: - v = 16
After doing so, change the sides on both sides of the equation, v = -16
So, your answer should be v = -16
