By meaning more than one variable on one side I figure that you mean the same variable.

For example: let x be the the variable.

4x+7-3x=47

If you have two variables on the same side you take them and either add or subtract them.
So 4x-3x. In this case you subtract and you get x by itself.

x+7=47

Now you subtract 7 from both sides

x+7=47
   -7  -7
---------

x=40</PRE>
