Teaching Equations to Pre-Algebra Students

I got in a heated discussion the other day with a couple of colleagues about how to teach equation solving to pre-algebra students.  The equation x + (1/2) = (3/4) came to mind because generally I start a discussion of equations by showing examples of one-step equations.  However, this equation (or most equations with fractions for that matter) is special because the quickest way to solve it may not always be the easiest way to solve it.  This can cause a dilemma if I am discussing one-step equations, but NEED to show the students two step equations in order to make the problem easier to understand for the students.  Does anyone else have an opinion on this?  Any input would be greatly appreciated.  Thanks.
