Select all that are true for solving one-variable equations:

• Anything you do to one side must also be done to the other to keep the equation balanced.

• To solve the equation, you must isolate the variable on one side of the equation.

• The variable disappears when you're done solving an equation.

• It is good practice to simplify both sides of the equation (combining like terms, distributing as needed) as much as possible before trying to solve the equation.

• When solving an equation, you should always cancel out any multiplication/division first before you cancel out any addition/subtraction.
