\"+3x%2F7+-+5x%2F3+=+2%2F21+\"
\n" ); document.write( "Since the denominators of all three fractions are factors of 21, multiply each one by 21
\n" ); document.write( "\"+%2821%293x%2F7+-+%2821%295x%2F3+=+%2821%292%2F21+\"
\n" ); document.write( "reduce the fractions
\n" ); document.write( "\"+9x+-+35x+=+2+\"
\n" ); document.write( "Combine like terms
\n" ); document.write( "\"+-26x+=2+\"
\n" ); document.write( "divide by -26
\n" ); document.write( "\"+x+=+-2%2F26+\"
\n" ); document.write( "reduce
