You can put this solution on YOUR website! You can't solve an expression!!! You can only solve for a variable in an EQUATION. How to do this really depends upon the type of equation.
For help with HOW to solve equations, see my own website. Click on my tutor name "Rapalje" anywhere in algebra.com. On my information page, click on the link to my Homepage. Once you find my Homepage, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time." Then choose "Basic Algebra". To solve LINEAR (ordinary!) EQUATIONS, see Chapte 1, Section 1.08. To solve QUADRATIC EQUATIONS, and look for this topic in Chapter 2. To solve FRACTIONAL EQUATIONS, look for this topic in Chapter 3. There you will find a detailed explanation of each topic, complete with examples, exercises, and most importantly, ALL of the answers. Many of the exercises in these sections are explained IN COLOR in the corresponding "Math in Living Color" pages. My own students used to think my explanations were a LOT easier to understand than the traditional textbooks. You might like my website for an alternative explanation, or for extra problems for practice! It's all FREE. If you get tired of math, then see the Joke Page!! If you like it please recommend it to friends.
