Algebra.Com's Answer #664364 by ptaylor(2198)![]() ![]() 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 \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
