You can put this solution on YOUR website!
Let x=numerator
\n" ); document.write( "Then x+4=denominator
\n" ); document.write( "Soooo
\n" ); document.write( "add 4 to numerator=x+4
\n" ); document.write( "add 7 to denominator=x+11
\n" ); document.write( "Our equation to solve then is:
\n" ); document.write( "(x+4)/(x+11)=1/2 multiply both sides by 2(x+11)
\n" ); document.write( "2(x+4)=x+11
\n" ); document.write( "2x+8=x+11
\n" ); document.write( "2x-x=11-8
\n" ); document.write( "x=3-----numerator
\n" ); document.write( "3+4=7-----denominator
\n" ); document.write( "CK
\n" ); document.write( "(3+4)/(7+7)=7/14=1/2
\n" ); document.write( "Hope this helps----ptaylor\r
