You can put this solution on YOUR website!
You can not simplify like the way that you did. You have to factor the numerator and denominator separately as below:
\n" ); document.write( "15x + 21 = 3(5x + 7)
\n" ); document.write( "9x + 15 = 3(3x + 5)
\n" ); document.write( "To simplify: just cancel out the constant term \"3\" from the denominator and numerator.
\n" ); document.write( "So (15x + 21)/(9x + 15) = (5x + 7)/(3x + 5)
\n" ); document.write( "John10:)
