In order to add or subtract fractions, they have to have the same denominator.

\n" ); document.write( "Simplify variable expression:\r
\n" ); document.write( "\n" ); document.write( " $\"%28-1%2F2%29x+-+%281%2F3%29x\"$
\n" ); document.write( "This has a LCD (lowest common denominator) of 6. Whatever you do to the denominator to get 6 you have to do to the numerator.
\n" ); document.write( " $\"%28-1%2A3%2F%282%2A3%29%29x-%281%2A2%2F%283%2A2%29%29x\"$
\n" ); document.write( " $\"%28-3%2F6%29x-%282%2F6%29x\"$ Combine the numerators, the denominator is the same.
\n" ); document.write( " $\"%28%28-3-2%29%2F6%29x\"$ When the signs are the same, add and keep the sign.
\n" ); document.write( " $\"%28-5%2F6%29x\"$
