Which is the most efficient way to solve this equation? X + 7 = 12
○Subtract 12 from both sides of the equation so all terms will be on the same side of the equal sign. ○Add -7 to both sides because that will result in an equivalent equation with x alone on one side ○Nothing, because the equation is already solved ○Add 7 to 12 because x equals 19.
That would be most efficient. Subtracting seven from twelve will quickly give you your value of x without moving the x itself. And there's no negatives
