You can put this solution on YOUR website!
I'll do 56, which looks tougher, and you can do 48.
\n" ); document.write( " 5/(x+6)+2/(x^2+7x+6)=3/(x+1)
\n" ); document.write( "1st we factor: x^2+7x+6=(x+6)(x+1)
\n" ); document.write( "5/(x+6)+2/(x+6)(x+1)=3/(x+1)
\n" ); document.write( "multiply (x+6)(x+1) times both sides to get rid of the fractions.
\n" ); document.write( "5(x+1)+2=3(x+6)
\n" ); document.write( "5x+5+2=3x+18
\n" ); document.write( "5x+7=3x+18
\n" ); document.write( "subtract 3x and 7 from both sides. 2x=11
\n" ); document.write( "divide 2 into both sides. x=5.5
\n" ); document.write( "Check:
\n" ); document.write( "5/(5.5+6)+2/5.5^2+7*5.5+6=3/(5.5+1)
\n" ); document.write( "5/(11.5)+2/(30.25+38.5+6)=3/(6.5)
\n" ); document.write( "5/11.5+2/74.75=3/6.5
\n" ); document.write( ".4348+.0268=.4615 approx
\n" ); document.write( ".4616=.4615 (.0001 rounding error)
