$\"%287%2Fx+-+2%29+-+%283+-+x%2Fx%29\"$
\n" ); document.write( "Any number divided by itself, like x/x, is 1:
\n" ); document.write( " $\"%287%2Fx+-+2%29+-+%283+-+1%29\"$
\n" ); document.write( "3-1 = 2
\n" ); document.write( " $\"%287%2Fx+-+2%29+-+%282%29\"$
\n" ); document.write( "-2 - 2 = -4
\n" ); document.write( " $\"7%2Fx+-+4\"$
\n" ); document.write( "To subtract we have to have the same denominator:
\n" ); document.write( " $\"7%2Fx+-+4%28x%2Fx%29\"$
\n" ); document.write( " $\"7%2Fx+-+%284%2F1%29%28x%2Fx%29\"$
\n" ); document.write( " $\"7%2Fx+-+%284x%2Fx%29\"$
\n" ); document.write( "Now we can subtract:
\n" ); document.write( " $\"%287-4x%29%2Fx\"$

\n" ); document.write( "If the problem was
\n" ); document.write( " $\"7%2F%28x-2%29+-+%283-x%29%2Fx\"$
\n" ); document.write( "then please use parentheses around multiple term numerators, like 3-x, and denominators, like x-2. For example:
\n" ); document.write( "7/(x-2) - (3-x)/x \n" ); document.write( "

\n" );
