You can put this solution on YOUR website!
\"%28x%2B3%29%2F%28x%2B5%29=%28x%2B1%29%2F%28x%2B2%29\"
\n" ); document.write( "You can cross multiply when you have a fraction equal to another, however multiplying both sides by the LCD works every time for rational equations.
\n" ); document.write( "The LCD is (x+5)(x+2)
\n" ); document.write( "
\n" ); document.write( "The denominators cancel:
\n" ); document.write( "\"%28x%2B2%29%28x%2B3%29=%28x%2B5%29%28x%2B1%29\"
\n" ); document.write( "Foil and solve:
\n" ); document.write( "\"x%5E2%2B2x%2B3x%2B6=x%5E2%2Bx%2B5x%2B5\"

\n" ); document.write( "\"highlight%28x=1%29\"
\n" ); document.write( "*Note* Always check and make sure that your answer does not make any denominator 0...that makes fractions undefined. If you had gotten -5 or -2, then there would be no solution.
