When describing the goal of solving equations, some say "Get x by itself." Most likely, what they mean is ___________

• Perform a series of steps until the equation is in the form $x=$

• Getting x by itself is cruel. No one says that anymore. #Getwoke

• If you wait long enough, the equation will solve itself

• I have never heard anyone say that and, believe me, I always pay attention in class
