-4v-12=-12-4v I need so much help

all real numbers

Step-by-step explanation:

-4v - 12 = -12 - 4v

Add 4v to both sides. Add 12 to both sides.

0 = 0

Since 0 = 0 is a true statement and has no variables, that means the equation has an infinite number of solutions. Every number is a solution of this equations.
