Math & Science ⇒ Basic Algebra

[Mikerada6]

I am trying to make a beamer presentation for my class on the basic methods of algebra. Basicly i want to be able to take an equation like 5x+3=2x-5 and show step by step that you subtract 5x from both sides and thenn add 5 to both sides. I would like to be able to "line up" the "x's" and "numbers". I tried using the align feature however it puts a large gap between the alignment &.

You might try either an array or matrix environment. Or possibly alignat. Voss's mathmode document would describe the various options.


(E.g -- requires amsmath ... )

Code: Select all

\[
\begin{array}{@{}r@{\,}c@{\,}r@{\,}c@{\,}r@{\,}c@{}r@{\,}}
 5x&+&3&=& 2x&-&5\\
-5x& & & &-5x& & \\
  0&+&3&=&-3x&-&5\\ 
  0&+&3&=&-3x&-&5\\ 
   &+&5& &   &+&5\\
   & &8&=&-3x& & \\
\end{array}
\]
