If there are variables on both sides of the equation, you need to eliminate one of them by subtracting it from both sides.
If you see parentheses ( ) with a number directly in front of them, that means you need to distribute, or multiply, that number on the outside of the parentheses to each variable or number on the inside of the parentheses.
If there are more than one term with the same variable raised to the same power, you must combine, or add, them. If there are more than one constant term, you must combine, or add, them too. (Remember, you cannot combine like terms across the equal sign.)
If there are terms being added or subtracted, you must "undo" this operation first. (Remember, whatever you do to one side of the equation, you must do to the other side too.)
If there is a variable that is being multiplied (has a coefficient) or being divided (it is the numerator of a fraction), you must "undo" this operation. (Remember, whatever you do to one side of the equation, you must do to the other side too.)
