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.

subtracting 7 from 12

Step-by-step explanation:

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
