Question

Which of the following describes the correct process for solving the equation 2x - 6 = 22 and arrives at the correct solution?

Divide both sides by -6 and then add 2. The solution is x = 8.

Subtract 6 from both sides of the equation and then divide by 2. The solution is x = 7.

Add 6 to both sides of the equation and then divide by 2. The solution is x = 14.

Add 6 to both sides of the equation and then divide by 22. The solution is x = -14.

Answer 1

To "solve the equation" means to isolate the x, so you get x={something}. So really the question is, what algebraic steps will get x alone on one side of the = sign.

Answer 2

To "undo" addition you subtract, and to "undo" addition you add.
To "undo" multiplication you divide, and to "undo" division you multiply.

Answer 3

And you want to FIRST get the TERM with the x in it alone (by adding/subtracting any terms that don't involve x), and THEN use multiplication or division to "undo" any coefficient on x.
